In the NFL, rules state that the uprights must extend for at least 20 feet above the crossbar.
There are two uprights.
Yes. The uprights mark the width of the scoring area, which extends infinitely upward. In modern NFL football, the uprights have been increased in height, and a rule change for extra-point conversions has reduced the number of these kicks that have to be adjudicated because they pass so high above the goalposts.
No. In NFL football, once a ball hits the uprights (goal post), whether from a pass or a missed field goal or a punt, it is out of play.
David Akers longest successful field goal went bouncing in the uprights 63 yards against the Packers in Week 1 of the 2012 season tying the NFL field goal record.

"To split the uprights" refers to successfully kicking a field goal in American football by sending the ball between the two goalposts, which are referred to as the uprights. It is a common way to score points in the game.
By rule, if you kick the ball during a scrimmage down, it's called a "scrimmage kick." If a scrimmage kick off the ground goes through the uprights, it's a field goal. Technically, there is no rule that defines a field goal "attempt." You don't necessarily have to "attempt" a field goal when placekicking on a scrimmage down, but if your kick doesn't go through the uprights, the same rules apply as would for a missed field goal.
The actual structure of the goal posts may vary, but by rule the only difference is the distance between the uprights. In college (and the NFL), they are 18 feet 6 inches apart. In high school, they are 23 feet 4 inches apart.
The two uprights are treated as if they extend upward to infinity. So the height of the ball as it passes over/through the uprights does not matter.
