Yes! Multiple clients can connect on the same port on SSH, or indeed
most any internet-enabled service. This is in the same manner such that
everyone can connect to Apache on port 80 if it were not firewalled. A
computer uses virtual ports to decide which application is listening to
which traffic. Imagine if the Google servers needed a separate port for
every single user...
If you'd like to learn more about networking, I'd highly recommend the
book "TCP/IP in 24 hours" by Joe Casad, which is a dry but extensive
look at the primary aspects of networking. It helped me greatly when
trying to understand various VPN setups and other server work.
