Foul after shot

[packersowner]

I tried to find any case plays on this in two different books and did not have any luck. It seems like I should know this, but I have the feeling of doubt in my head, so asking for a little help here. This happened 4 times the other night and I am not sure we got it right.

A1 is shooting a 3 pointer and is contacted during the shot as the ball is being release, basket is no good.
Our call: A1 is shooting 3 FT's. I think we got this one right

A1 is shooting a 3 pointer and is contacted after the ball is released but before he returns to the floor, basket is no good.
Our call: A1 is shooting 3 FT's

A1 is shooting a 3 pointer and returns to the floor, B1 bumps A1 and causes him to fall down. Basket goes in.
Our call: Basket good, foul on B1, A1 ball under the basket.

A1 is shooting a 3 pointer, A2 fouls B1 after the ball has been released.
Our call: Basket good, foul on A2, Team B's foul under the basket for a throw in.


Help!!! Which ones did we get right/wrong?
