A few of the screen scenarios I've seen:

An offensive player sets a screen on the ball handler's defender. When the defender attempts to go around the screener, the screener moves with the defender to impede his movement toward the ball handler. I guess this could be holding, blocking or pushing depending on his action to impede the defender. If the screener turns away from the defender and continues with ball carrier but unintentionally screens the defender then no foul?

What criteria must be met to set a screen behind a defender?

Screener must allow a normal step by the defender when he is not visible to the defender, either behind or to the side.

Can two offensive players set a screen on the same defender at the same time?

Yep

NF rules: On a free throw, is it a violation to enter the lane before the ball touches the rim or backboard?

Thanks.

Under NF ball must hit the rim before the players can eneter the lane.
