The starting point is the bath house, which is the lowest point on the map and where the high speed fiber connection is... the Cat 5 cable from there can be easily directly connected to a router. The next challenge is to get that bath house signal up the hill to the barn, which is the summit of the property. There IS direct line of sight, so a bridge would work for that purpose.
The lines from that barn indicate the amount of feet to all the buildings which need WiFi service. Given that satellites only give around 15000sf of coverage, that translates to a direct line of around 85 feet... not enough to get to the places needing service. Is it possible to create 10+ bridges to those places from the barn? Do I need a router at the end of each bridge to pipe out WiFi? Is there any type of hardware (router, POE adapters, antennas, etc.) that you could suggest to accomplish this goal?
Any chance their all wired together? With ethernet or fibre?
Your other option would be to connect them with something like netgears Airbridge for connecting the buildings. It wouldn't provide access in the buildings, you'd need access points for that, but it could be used to connect them.
And then just setup an access point or orbi for each building that needs coverage
