I think Jonah is a static character because he wants to keep finding out what he has to do with the plane. He takes the time to have that meeting with Angela DePure to find out what is going on. He interviews all the kids at the event if they know anything about the plane. Finally, he has every kid in the cave interview Gary, Mr. Hodge, JB, and Angela.
I think Chip is a static character because he wants to keep finding out if other people did not know they were adopted. He calls almost every person on the survivors list that has their phone number on it. He also gets this meeting with Angela DePure to find out more about his and Jonah's adoption. That is why I think Chip is a static character.
Dynamic character not static character.
