In the rule book
The Greek word for "rule" literally means "to umpire".
This is rule 5.10, which states, in essence, that the umpire shall call "time out" in certain situations. An important part of the rule is that no umpire shall call "time out" while play is in progress except in case of light failure or when an accident incapacitates a player or umpire. Also, commonly mis-understood, is that only an umpire can call time out; a coach or player can only "request" time out, which must be granted by the umpire before the time out actually occurs.
You have to be an asa umpire to recive the rule book.

The answers are in your rule book. READ IT and it will tell you the answers.
Any umpire may indicate the infield fly rule is in effect by yelling "Infield Fly" and extending his right hand above his head and pointing. However, the infield fly rule is in effect whether or not any umpire does this.
If you are talking about baseball/softball, then no, on the 3rd strike called by the umpire, the player/batter is out.
No runner is allowed to be touched while running the bases. Only a bad umpire would enforce this rule on a high five. There is no rule that prohibits touching a runner, but there is a rule prohibiting physically assisting a runner.
No, a ground rule double is ruled by an umpire, and once it is ruled, then it is a double. You may have a case where a ball gets stuck under the padding on the outfield wall, or stuck in the ivy at Wrigley Field, where the fielder will put his hands up asking for a ground rule double. In this case if the umpire does not rule immediately base runners will continue running, when the batter reaches home, the umpire will go out and determine if in fact it is a ground rule double if the ball is actually lost in the ivy of Wrigley Field, or at other ball parks, if the ball is actually stuck under the wall padding. It is up to the umpire at that time to decide if it is a home run or a ground rule double. However, most ground rule doubles involve a ball that is fair and bounces into the stands, if this happens, it cannot be a home run in anyway
