For TCP, no. You can only have one application listening on a single port at one time.
Now if you had 2 network cards, you could have one application listen on the first IP and the second one on the second IP using the same port number.
For UDP (Multicasts), multiple applications can subscribe to the same port.

For Linux and TCP, yes. Child processes can inherit that socket (see how Nginx does with its workers). You can also pass sockets around.
