The best thing to do is to use netstat. As root, if you do:
netstat -p -a -A inet
This will list all the processes that are bound to certain ports. Depending on how active is your system, you might get a lot of output. In that case, I would also pipe that to grep LISTEN (squid will be probably running in listen mode, attached to an endpoint).
netstat -p -a -A inet | grep LISTEN

What program or possibly how can I check what service is using which port. I'm trying to set up Squid to use port 80 and I'm getting an error that the port is in use
