Be very careful doing deadlifts and squats' if you've never been in a gym before. I'd personally leave these out for the time being, and gain some more knowledge first, as if you injure your back now, the chances are it could haunt you for a very long time.

Dumbbell pressing is very similar to barbell bench press, and I personally would do this until he gets to know people and can ask for a touch, as if he can't get the weight up, he can just drop them to the floor pretty easily.
