realms and virtual server does not necessarily have one-to-one
mapping, but yes, you can have many virtual server in FR, and one (but
not the only) way to select which one to use is by using realms.

pretty simple.

If by ADS you mean Active Directory, no.

You need to either:
- setup FR to authentication using AD (see
http://deployingradius.com/documents/configuration/active_directory.html),
OR
- proxy it to a radius server that gets data from AD (e.g. MS
IAS/NPS), not proxy it to the AD.

Some of it might be possible using the default virtual server and
unlang, but it should also work using realms and many virtual servers.
