Well, without a bench you haven't got much of a choice when it comes to Chest exercises. The only ones I can think of are Dips where you lean forward and weighted Pushups. Both are more for endurance than muscle building.

Other than that you should be alright. Off the top of my head:
Biceps: Dumbell Curls
Triceps: Tricep Extensions, Tricep Kickbacks
Deltoids: Lateral Raises, Front Raises, Shoulder Press
Back: Bent-over Rows, Weighted Pull-ups, Weighted Chin-ups
Legs: Squats, Lunges, Calf-Raises
