1. They were triplets.

2. ......... They were playing Monopoly? (This is the answer we ALWAYS hear in class when boys answer lateral thinking)

3. Umm, he died of dehydration? The sweat from his body left while running halfway back? He didn't drink enough water?

4. White. His house was at the North Pole.

Just random guesses (most of them. I've heard 1 before, and a very similar puzzle to 4)
