yellow and there called uprights
Goal posts, commonly referred to as "uprights."
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.
The goal post dimensions in Canadian football are the same as in American football. The goal posts are on the goal line. The hash marks are not in line with the uprights.
6.4 Metres.
An ambiguous question. Posts of the same goal or posts from opposite goals?
The distance between the goal posts is officially 7 yards; so that is 21 feet. In metric that is 6.4 metres. The width of the goal posts themselves is not official, so this might vary; but the rule states that at lest the bottom 2 metres of each post must be padded as protection. In some grounds, the base of the posts can be even 8 or 9 inches thick due to the padding.

Too far!
360 feet.
The football, after being kicked by the place kicker, must travel over the crossbar and between the two uprights of the goal post. It can hit one of these bars, but it must then bounce in such a way that it still goes over the crossbar and between the uprights. There is no limit on how high the football can go. The "uprights", though they have a finite physical length, are considered, for the purposes of the game, to extend upward infinitely.
