WR gets a tie catch.

By definition, a ball "in the air" is a loose ball, and therefore no one has possession. However, depending upon the circumstances, it's possible that only one team has the right to gain possession (for example, a punted ball).
A held ball in basketball occurs when two opposing players have simultaneous possession of the ball, resulting in a stalemate. Referees call a held ball by blowing the whistle and signaling a jump ball situation, where the possession is determined by a jump ball between the two players involved.
Yes. According to the (new) NFL rules a receiver must maintain possession of the ball all the way to the ground.
In the NFL, if you bobble once and drop the ball before retaining possession, it is an incomplete pass. However, if you bobble, gain control over the football and take two steps before dropping the ball, it is ruled a fumble, and the ball is available for either team to recover and gain possession.
Answer Yes.
It signals a change in possession of the ball.
In the NFL, a fumble recovery occurs when a player gains possession of the ball after it has been dropped or lost by the opposing team. The player who recovers the fumble can advance the ball, and possession is awarded to the recovering team. If the fumble occurs in the end zone, it can result in a touchdown or a touchback.
The defense will have the ball at their own 20 yard line.
It depends on whether or not he has the ball in his hands when he hits the ground of the endzone. If it is not in his possession, then it is a fumble and can be recovered by a defender. If it is in his hands and he touches the endzone, then it is a touchdown. If he was in possession of the ball when the ball crossed the goal line, it's a touchdown. As soon as the ball breaks the plane of the goal line, the ball is dead and the play is over. Anything that happens after that is irrelevant.
Yes. In both college and the NFL, if a field goal attempt does not cross the line of scrimmage and is recovered by the kicking team, they will continue with possession of the ball. This ruling doesn't really come into play on 4th down kicks because the kicking team will lose possession of the ball on downs. But on third down, if a field goal attempt is blocked and the ball does not cross the line of scrimmage, should the kicking team recover the ball they keep possession and it will be fourth down. If the ball crosses the line of scrimmage, possession goes to the defense.
When a player advances a fumble in the NFL, it means they pick up the loose ball and run with it. If the player who recovers the fumble advances it into the opponent's end zone and scores a touchdown, the team gets possession of the ball at the spot of the recovery.
