Just wondering if its possible to have 2 different DNS servers on a server? For instance i am running BIND DNS (Through cPanel), and wish to run a separate instance of PowerDNS as well. Is this possible? Can i do this with 1 IP? Or do i need 2? Or is it not possible to do this with a cPanel BIND?

I have not tried anything as of yet as i don't want to ruin the DNS currently in place.

You cannot run two DNS servers on the same IP address (as both need port 53 on that IP address). However, servers are not restricted to one IP address (multiple interfaces, interface aliasing, etc.) so you could run a different DNS server on each IP address you have as long as you tell every DNS server which IP it needs to bind to.
