DNS Info!

Okay, I just needed to know if this is possible to do or not.

I have server hosts address for freewebs but I also bought space on hosting matters. Do I have to transfer the DNS to read as the hosting matters one to be the primary and secondary hosting address, or can I simply add in the hosting matters DNS server hostname along with the other two hostnames? Which would be in the end four host names.

Can you do that?
