I would like to prepare listner in another port but I have got problems you can see this in picture with I added below. Also I would like to connect to dabase using this “listener” and check connection in CMD using easy connect.

listener in 1521 is working but in another port I have got problem

“No listener” error indicates either that you’re reaching the wrong server, or the right server on the wrong port, or that the listener is not started. I would start by checking that the listener is started, since you can reach the other one.
