Possibility of using multiple devices on 1 account

Hello, my name is Adam and i’m a student at 

Secondary Industrial School of Transport in Bratislava, Slovakia. Me, my digital coordinator and our subhead are trying to get up with the systems of Meta Quest 2, to use them for educational purposes as of using simulator where you are fixing cars etc. We ran into a problem where there’s not known a possibility of using these devices on 1 account, or there’s a need to have an account for each devices for more compatibility. Could please someone help me with this? I would really appreciate having a video call for more information about this. Thank you very much for helping! Greetings and have a great day
