Foul After Shot

[actuary77]

Here's the situation.

A1 shoots the ball and is being guarded by B1. After the shot is released, (1) B2 fouls A2 as they jockey for position for a possible rebound; (2) A2 fouls B2 as they jockey for position for a possible rebound. The shot of A1 goes in in both situations.

For situation (1), will free throws be awarded to either A1 or A2 if Team A is not in the bonus? How many free throws? How about if they are in the bonus?

For situation (2), will the basket of A1 count? If Team B is in the bonus, will B2 get to shoot free throws?

Please indicate the ruling for both NFHS and NCAA, if different.

Thanks.
