2.) as Mrs. Kawasaki looked at the children on her Right, Since the word used is "children" that means it's many and when you use "them" it means you are gesturing to many/2 or more people.
3.) as Mrs. Kawasaki looked at the ship to her Right, since she is gesturing to the ship, and a ship is an "it" that means it has no gender.
