The player under the basket moves away, receives the ball (if the set-up is right, he receives the ball a bit diagonally), the player in front of the basket comes alongside and shoots.
Same as above, only now the player in front of the basket gets next to it again and makes a through ball from the space without the ball.
Same, only now no through ball is made, but there is a threat for the through ball and the player without the ball runs long (away from the puller and parallel to the basket) and makes the shot.
Same, only now the shooter runs long again, and after running the long line comes through for the walkthrough ball without the ball.
