Of course BIND can do all of this.  It is the reference implementation
for DNS.

If you have multiple domains sharing a single network, then just
include the different hosts in the same ZZ.YY.XX.in-addr.arpa zone
file:

15		IN  PTR		wais.easterbunny.org
26		IN  PTR		gopher.santaclaus.org
31		IN  PTR		archie.rainman.org

If you have multiple domains on multiple networks, use a separate zone
file for each separately identifiable network:  e.g., 10.14.28.0/24
gets 28.14.10.in-addr.arpa; and 192.168.84.0/24 gets
84.168.192.in-addr.arpa.

I don't quite understand your last, though.  It is almost always the
case [except in the rare instance of stealth primaries] that a
"primary" or "master" DNS server is one of the DNS servers for the
computers in its domain.

Fair 'nuff?
