Once you get off the plane you arrive in an area that has big LCD screens and sign boards that point you towards transfer, immigration, etc, as well as some AF kiosks, I think, to get your next boarding pass, if you're transferring on AF. You could, probably, loiter here for a while, but if I were you, I'd cross immigration and wait out at the luggage belts. Pick up your luggage, then find out where your friend's luggage will be sent, and wait there.
If you leave your luggage unattended too long, no telling what's going to happen to it...
