Making Stroke While Another Ball In Motion

[BC MIST]

STROKE PLAY

Mike is on the putting green 50' from the hole.

1. Dave is on the putting green 25' from the hole and plays while Mike's ball is still moving.

2. Dave is on the fringe 40' from the hole and chips while Mike's ball is still moving.

3. Dave is in a bunker 40' from the hole, cannot see Mike, and blasts while Mike's ball is still moving.

4. Dave is on the green 25' from the hole, plays, and while his ball is moving, Mike plays.

What are the penalties in each situation, if any?

I suck at knowing all the rules but as long as they don't hit each other, why would it matter? On weekend rounds I'll hit right after one of my friend hits before their ball has landed and come rest just to speed things up. What's the technical penalty for that?
