Before I tackle a new project, I would like to know if what I want to attempt is possible using a single Arduino.
I would like to build a puzzle involving four items containing RFID fobs. As each item is placed in the correct location on a table, a mag lock will be triggered. (Note each correct placement triggers a mag lock, not required for all four to be in place at once)
Can this be done with one Arduino or will each RFID sensor require a separate Arduino?
Thanks
Seems possible with one Arduino, if you make the correct choice of board.
My assumption is one, but you can answer your own question with very little work. Just find a reputable RFID library and check samples, but if that doesn't reveal the answer, then reading the library source code will if it isn't documented.

From first appearances I think you have hit the nail on the head!! I will explore this deeper, Thanks!!
It helped me, but did not address my key concern, that is the challenge (I assumed) of having multiple readers within a small area.
