Waiting room : print and synch players

Hello everyone !

So i'm a beginner to Photon Unity Networking and I'm creating a multiplayer system inspired by Overwatch and LoL systems
When the players connect to photon, a menu appears with a "play" button. On clicking on this button, the player can chose custom properties for the game : game mod, game map, number of players ... and then can choose between create a room with these properties or enter in matchmaking with the same properties.
When the player choose to create a room, a new panel appears, showing him room properties.
That is the problem : I want to print infos of every players in this panel and, obviously, synchronise them ... but I don't know how to do this !

Any help would be really appreciate ! I can give you more details about my problem if needed

Thanks you really much !
