This is utterly wrong and pointless. Unless you can make the whole
world send queries to a non-standard port number just so they can
query your name server. This will never happen.

Correct. Each named process has its own named.conf file.

No. See above. You could make your name server do this but the rest of
the world will ignore it. Everyone else's name server software has no
way of knowing which non-standard port number you happen to have bound
to a name server.

Yes. Use the listen-on clause in the options{} statement to make each
name server process only listen for queries on a specific network
interface.
