Can Pun and Photon Sever be used together

I need Photon Sever to make a local server and I need to open the game after creating the room (like a board game).

I see that I need to use PUN to create a room, but I don't know if I can use PUN when I am using the local server.

Also, I was wondering if it is possible to make an Android app for multiplayer games using a local server?
