It doesn't matter how many times the ball is touched, as long as Team A didn't lose control, if they touched it last in the frontcourt, it is a backcourt violation for them to touch it first in the backcourt.
In your other example, team control for Team A ended when B1 gained control of the ball. Team A would have to re-establish team control in order to be able to call them for a backcourt violation.
