ruling?

[xxssmen]

1) Player A1 attempt a shot but miss evrything and goes and catch his/her airball and continued to dribble or shoot again legal or not?
I say its legal but my friend here say NO so can u give me the right answer for him?

2) Player A1 dribbling down the court and decide to pass the ball to A2 but see that his /her pass is going to be intercepted decide to hold back the pass but it slip out, so can player A1 go and retrieved the ball after he/she pass it off and decide to pass it again.
