But the ball never passed halfcourt!

so I don't need to make a new post on backcourt which there have been many.
1.OK so it is backcourt on a pass right? ball deflected by defense, b2. Ball then touched by a1 and rolls into backcourt and a2 gets it. Violation
2.Not a backcourt on a shot attempt?- Ball goes off the rim, hits off offensive player and goes into backcourt. A2 gets ball, violation?
3. If it is a rebound, A1 does a controlled tap to a guard who misses it but gets the ball in the backcourt would that then be a violation?
4.If it is a shot attempt and the ball is rejected and hits A1 and then into backcourt I assume it is not a violation because control has ended but I wanted to check.
