I believe windows has an simultaneous internet connection limit which you could override in the registry - perhaps Android has something similar?

Googling showed this might be possible using a mobile phone https://osxdaily.com/2013/07/30/bypass-d...i-hotspot/

My concern would be that, with so many devices, at least one wouldn't be working.
Also, what would you do if it totally failed when performing? (perhaps this is what you should be doing normally)

You will need to watch the data charges (assuming you can get the phone method to work)
