The short answer: no problem.

The short explanation: for each IP there are many "ports". Each service
has it's own port. Usually these are:

http = 80
ftp = 21
smtp = 25
ssh = 22

As long as you have only one instance of each you don't even need any
special config. Just install the respective package and be sure to open
the coresponding port in your firewall.

If you can't explain it simply, you don't understand it well enough.
