Hi,

I know that well knowns ports such as named, http,etc............
Can I able to use it for other applications? since I am not running those daemons.

Yes (is too short).

If the port already established and if I uuse that port on different application, which application would work?

You must be root to use ports below 1024.

If you try to bind to a port which is already in use, the listen system call will fail with error EADDRINUSE (already in use). See the listen(2) manual page.

The first one will continue to work and the second one will error out with EADDRINUSE.
