In American football, offensive linemen can be a maximum of 1 yard downfield at the time the ball is thrown on a forward pass. Beyond this yard, they would be considered ineligible receivers and an illegal man downfield penalty would be called.
No. It is illegal for an eligable man to block a defender past the line off scrimmage if the ball is in the air.
No, not unless he touches the ball, in which case the penalty would be illegal touching. Ineligible receiver downfield: 5 yard penalty, replay the down Illegal touching by ineligible: 5 yard penalty, loss of down
You cannot catch a punt while out of bounds in the NFL.
no
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.
Downfield F.C. was created in 1912.
That could mean a couple of things. On a pass play, offensive lineman (center, guard, tackle) are not allowed to cross the line of scrimmage prior to a pass crossing the line of scrimmage. This infraction is called ineligible man down field. On a punt, the only players on the punting team allowed to cross the line of scrimmage prior to the punt are the two players positioned on the end of the line. Should any other player except for those two players cross the line of scrimmage prior to the punt, the infraction is called ineligible man down field.
Downfield is "in or into the part of the field toward which the offensive team is headed," according to the Merriam-Webster dictionary (1), and is consistent with the use of "downfield" in the football penalty, Ineligible Receiver Downfield. Unfortunately, as of this date (10-23-11), Merriam-Webster has the same definition for upfield as it does for downfield (2)!

"Legal" receivers are elligable to catch a pass. Players who start a play on the end of the line or in the backfield are elligable. Linemen can't cross the line of scrimmage before a foreward pass crosses the line or they are considered to be downfield illegally unless the pass is caught behind the line of scrimmage.
