What type of snacks kids like?

My stepson and his cousins are coming soon to spend a week with us. I'm going to babysit them for a few days and I'm very excited with the idea. The kids are between 9yo-15yo. I want to have some snacks in the house but don't want to have those sugary unhealthy snacks. What type of snacks would you recommend? I was thinking of popcorn, finger sandwiches, cereal, yogurt, berries.
