I was a punter for a team in Ohio in 1998 and my longest punt was 75 yards.

Traditionally speaking one punts on a free kick (usually after a safety), because your average punt has a longer hang time than a placed kick. This allows the kicking team to get into position to tackle the ball carrier.
We cannot see your diagram so we do not know who Player R might be nor whether he or she can return a punt.
30.4 yards per punt
No, I personally have never heard that you could. If the other team gets a safety though, then they get 2 points and the other team then has to punt the ball to them from I think the 20 yard line.
a punt may be blocked by the kicking team without penalty unless there is some other illegal act involved. As long as the kicked ball is touched prior to the blocker contacting the punter the contact is ignored. For exanmple If the punt blocker were to block the punt and then make helmet to helmet contact with the punter there would be a penalty for the illegal helmet contact but not the blocking of the punt.
