Foul or Dead

[alwaysask]

ASA 12U - B1 hits the ball, while still in box the ball hits the bat in B1s hands for a second time. Is this called a dead ball and add a strike with less than 2 strikes or is it a simply a foul ball. In this game the ump called her out, said it did not matter if she was in the box or not.

What if? B1 hits the ball and the ball hits the ground bounces into the air, the batter drops the bat and the ball hits the bat in the air out of B1s hands?

Whats the call in Fed on both of these?
