Dear Gayle,
Hear are some websites which may be of help in researching historic building in England & the rest of the UK. I've specifically commented on the More Arms as I believe that both the Malt House and the building used as the Arms still exist. See the paragraph below the (hopefully useful) web addresses.
"Researching Historic Buildings in the British Isles"
This website is very good for the whole process of researching historic buildings but I suspect you might already have taken many of the steps in its recommendations. However, if you haven't, here is its website address.
https://www.buildinghistory.org/
This website provides a gateway to many other websites.
Historic England: Further Resources to Help You Research Your Home's History
https://historicengland.org.uk/advice/your-home/your-homes-history/further-resources/
This website has references to the Upper Bent farmhouse buildings, which tend to suggest that the owners have made a number of alterations to the site. It also tends to show that the best place for finding information on Historic buildings in Shropshire is the Shropshire Archives! By the way, it almost certainly also contains references to your other buildings of interest, I just happened to take a look at what it had for Upper Bent!
Heritage Gateway
https://www.heritagegateway.org.uk/gateway/
I don't know how much of the Shropshire archive's resources are available online but you can at least contact them via the website and find out. Your best option might be to find a fellow Lost Cousins member who is interested in visiting the Shropshire Archives for you. I think that in the end, to get really detailed information may well need a visit to the archives but, you never know until you try!
Shropshire Archives
Discovering Shropshire's History
https://www.shropshirearchives.org.uk/
Always worth a visit for anything English heritage, possibly to join English Heritage and it may well offer a good chance of finding a researcher who might undertake a visit (or visits) to the Shropshire Archives or The National Archives for you.

If you can get a view of the buildings via Google street view (see below), this website may be of interest.

The More Arms Inn probably does still exist as a building or buildings, as, in such isolated spots as More, buildings don't usually get demolished but merely extended/partially re-built and re-purposed.
If you use Google Maps (
https://www.google.com/maps/@54.5512799,-4.4737716,5z) and type the following Latitude & Longitude into the map search box <52.51719483728808, -2.969300139262032>, you will be taken to a house now called "The Malthouse" in More and if you then use the "little yellow man" to get a street view of this house, you will see that there are a pair of very old wooden doors toward the middle of the building, above which there is an old sign (which can just about be read when zooming in to the image), which reads in white lettering on a black background, "JOHN MORRIS LICENSED MALTSTER"! This must have been the old maltings and possibly another part of this building operated as the Inn but my money would be on the "cottage" next door on the Western side, which is now called "More Cottage" having been the Inn!
One possible avenue for beginning investigation of the buildings might simply be to write to the present owners, stating your connection with the building and asking them whether or not they know any of the history of the building or whether there is someone locally interested in historic buildings who might be interested in helping you. For this you need the correct postal addresses, which, in this case is -
"The Malthouse", More, Lydham, Shropshire, England, SY9 5HH United Kingdom. (The Postcode part of the address shouldn't be omitted)
You could try this for any of the buildings you've asked about, except the Upper Bent Farm, for which I can't obtain a postcode from either the "Royal Mail" website post code finder at <
https://www.royalmail.com/find-a-postcode>, or the "UK Grid Reference Finder" website at <
http://www.gridreferencefinder.com/> but its Lat/Long is <52.533097779034215, -2.980153360038542> & its address ought to be "Upper Bent Farm, Upper Bent, More, Lydham, Shropshire, England, United Kingdom" but without postcode! The Google maps street view of the farm buildings is heavily obscured by the hedges in leaf from the Sep 2021 view but an alternate dated view from Dec 2009 gives a better view (with obviously no leaves on the trees/shrubs), which can be accessed by clicking the "see more dates" label in the panel, upper left of the street view window.
The Crown Inn, Wentnor, Salop, is clearly visible in a Google street view of the following Lat/Long-
Lat, Long: <52.529137294661815, -2.9091992104105917>
Postal Address: The Crown Inn, Wentnor, Shropshire, England, SY9 5EE, United Kingdom
I can't find a farm on the present day Ordnance Survey maps which is called "Norbury Farm" but it has possibly been re-named or changed to being simply a domestic building(s). However, if you care to search for it on old Ordnance Survey map at The National Library of Scotland website <
https://maps.nls.uk/geo/find/>, you can find, "Brow Farm", "Hall Farm", "Freehold Farm", "Lea Farm", "Glebe Farm" & "Walkmill Farm" in Norbury Parish, "Hall Farm" being of course the largest! If you can work out which of these was "Norbury Farm", you should be able to find its address and postcode at the "UK Grid Reference Finder" website, by transferring its location from the old Ordnance Survey maps to the Google maps website where you just right click on the location, whereupon a window will appear with a Lat & Long in it, just left click on the Lat,Long which copies it to the clipboard and then paste it into the Lat/Long boxes of the UK Grid Reference Finder, which will then give you a postal address for it! If Norbury Farm was the Hall Farm, its several buildings look (from a Google street view) to have become several domestic dwellings, so finding the correct postal address for each one could be tricky.
Hardwick Hall Farm & Cottages can be found either side of the road here at Lat/Long <52.50948945211746, -2.9314824275594122> postal address (I think) "Hall Cottage", Norbury, Shropshire, England, SY9 5HS, United Kingdom. The Hall cottage itself can't be seen from the Google Street View, because it's hidden behind a high hedge and shrubs but the farm buildings and old labourers cottages are clearly visible on the western side of the road.
Since I composed this reply, I think some of the links given here have already been covered by other members, whilst I was being registered as a forum member. So, I hope you'll forgive any repetitions I've given here!
Good Luck,
Chris Morris
N.B. Although I'm also named Morris, I don't think that there's any relationship between us as my great grandfather Morris came from Presteigne in Wales and in the 1881 census, Morris was (I think if I've remembered correctly) the 14th most common surname in England & Wales. Being from the "Black Country" of the West Midlands of England, local surnames of Welsh heritage are very common e.g. Hughes, Roberts, Edwards, Davies, Williams, Evans, Lloyd, Price/Preece/Reece/Rees, not forgetting Morris etc, etc.
