Each seat has its own supply. Otherwise it's not a legal seat.(there are certification requirements to carry passengers)
If your mask doesn't deploy for you, the theory is sound that you could share a mask. Good luck getting it to happen. Then again, it would give you something else to think about and work on during the crisis so that would be good.
