When you play a shot from a bunker and hit it out of bounds, you clearly have to replay your shot. But the rules stipulate that the conditions of the previous shot must be recreated. So if you played from sand which was raked, you would rake the sand and place the ball as close to where the last shot was played from in the last shot. If you were in a footprint you would have to make a footprint and place your ball in it, and if you were in a divot, you would make a divot and place the ball in it.
No, because this is viewed as testing, for which you would be given a penalty.
Nope
Get into the bunker, play their shot then rake the bunker as they are leaving.
No, once you are in a bunker, you may not rake it or ground your club until you are out of that bunker. If you rake the bunker when your ball is still in it, you receive a two shot penalty or loss of the hole in match play.
Tap the bottoms of your shoes with your club so the sand goes back in the bunker and then rake the bunker with the rake provided.

Yes, absolutely. Each bunker is considered an individual hazard, not a collective hazard of bunkers. If you play out of one bunker and land in another, you may rake the one you have just played from. Note, there is a common misconception that if you are in a bunker and rake footprints before you play your shot you are penalised, this is not the case, you are only penalised if you improve the lie of the ball, your stance or test ground conditions.
The Rake.
Yes, you may do this, but set it down gently and out of the way, just in case someone accuses you of testing the surface.
Yes as long as you repair the markings you have made with your shoes or golf clubs
No, you are not allowed to do so, you must not rake the bunker or smooth sand over with your feet, as this is deemed to be improved your stance or testing the ground conditions. You will get a two shot penalty for testing, if you do so.
