Can you use 2 GFCI outlets on the same circuit?

Yes, there are several ways to wire them. If you only want some plugs to be GFI (only the actual GFI plugs) protected then you wire them using just the "load" screws. if you want the whole circuit to be protected (or just two separate portions) the GFI plug must be first in the circuit and the protected plugs wired off of the "line" screws on the receptacle. Check the instructions, local codes, and with an electrician of course. Be safe, GFI circuits can be tricky.
