Well hey since I'm probably not going to send my answers to nobody.. I'll just answer them here :jointsmile:

1. The 4th dude from left to right at the bottom row.. with the golden button on the collar.
2. I'd say the 1st and 3rd kid from left to right bottom.. the 2 bigger dudes, not the one behind, hah. Then the 2 guys on the right side as well. I think there are 2 pairs of twins.
3. Same here, 2 pairs. The 2 left ones, and the 2 right ones behind.
4. Hahaha, this one is hilarious... I'd say 9.
5. The lady in the white shirt is the teacher.
