I agree completely on situations 2 & 3, but I have a question on situation #1. Typically when there is a potential play from RF to 1B, the runner is running through the bag, similar to a ball to the infield. If she is rounding the bag on that play, it seems to me she is attempting to interfere with the play from RF (especially since the same kid was involved in all three instances of contact).
How would this situation be any different from a ground ball to deep SS and having the runner round the bag at 1B and run into F3 receiving the throw from F6?
