All of these use CPU resources, and regarding the port it is the transport which occupies port.

Yes you can have n number of person in one meeting if your architecture supports it.

I think you are more concerned about the port usage, and are worried if the ports can get short. No need to worry about it, in latest version of mediasoup you don’t need to specify port range, you just specify one port and everything happens on that, check here:
