Kids These Days

Hey, we asked a few kids to volunteer to help with this puzzle. The boys are Conrad, Jacob, Sammy (aka "Sam"), and William, and the girls are Beatrice, Kazuko, Lisa, Lisbeth, and Trisha. They're each supposed to be holding a distinct (integer) number from 2 to 10, and in a neat row from position 1 on the left to position 9 on the right, but we've been having trouble with them. I know you're not exactly on a first-name basis with them, but could you give it a go?
