Depends on the implementation.

In all cases, the -p argument given to the server will specify the number of ports. In Jack1 it defaults to 256 but can be increased arbitrarily. In Jack2, I don't know the default, but I do know that the upper limit is fixed at build time. In most cases it will be 2048.

counted towards the total.

Is there a difference between the number of ports registered, and the number
actually connected?

depends on what you mean by "connected"
