Yes,
You can play it anywhere that is in play(not OB)
If my "ball ball" lands in a tree and i find it, i play with it again. I mean, i already found it.
They play another hole. If they tie on that hole, they play another hole. And on and on until someone wins a hole.
If the ball lands inside the lines after is crosses 3ed base and rols out it is still "in play"
If you are on the green putting, and your ball strikes the pin in the hole or the ball is holed you receive a two shot penalty (Stroke play) and you play the ball as it lies. Or loss of hole in matchplay.
As long as the player isn't touching the ball when he lands in the crease, it is normal play. It is a free throw for the opposition if the player is touching the ball when he lands in the crease
Yes and No. This is covered by Rule 22-2 Ball Interfering with Play of the Rules of Golf. Except when a ball is in motion, if a player considers that another ball might interfere with his play, he may have it lifted. A ball lifted under this Rule must be replaced (see Rule 20-3). The ball must not be cleaned unless it lies on the putting green (see Rule 21). In stroke play, a player required to lift his ball may play first rather than lift the ball.
A batted ball that hits the pitcher's mound (or any base) is considered a fair ball. A fair ball that lands out of play is considered a ground rule double.
You use a club to hit a ball into a hole.
They either stop play where it lands or redo it
You take a free drop, one club length from the nearest point of relief, which would be the edge of the green no nearer the hole.
Check local rules for ruling. Usually you are allowed a free one club length drop, no nearer the hole, if the ball is on the sprinkler or your stance is affected. However, unless otherwise stated, if your line of play is affected you are not entitled to relief.
Your ball is replaced, as near as possible to where it was before it was moved, no penalty. Your opponent unfortunately has to play his ball as it lies, if it's in the water then so be it, he would have to take a penalty drop from the water.
