Illegal Dribble Scenarios

[RefBob]

I had an illegal dribble call recently and want to confirm my understanding of some scenarios:

1. While in the act of dribbling, A1 loses control of the dribble, the ball then bounces off A2 or B2, A1 regains control of the ball with two hands and then starts dribbling again. ILLEGAL DRIBBLE.
2. A1 while dribbling has the ball slapped away by B1. A1 regains control of the ball with two hands and starts dribbling again. LEGAL. (Rule 9-5-2.)
3. A1 ends their dribble. A1 then passes the ball and it touches A2 or B2. A1 regains control of the ball with two hands and starts dribbling again. LEGAL. (Rule 9-5-3.)
4. A1 ends their dribble. A1 then fumbles the ball and the ball bounces away. The ball then touches A2 or B2. A1 regains control of the ball with two hands and starts dribbling again. LEGAL. (Rule 9-5-3.)

Is my understanding of the above scenarios correct? Thanks all.
