Surface wind is disrupted by the contours of the earth, hills, tall buildings etc and so it swirls from different directions. As you go higher the air currents are affected by warm air rising and cooler air rushing in to fill the void. Higher still and you have the Jet stream. Its too high to be affected by the air currents etc and so bloes in a constant directs. Its a lot more complicated than that but it gives you the idea.

Wind generally move in one direction, there are slight cross-winds but the main difference is that on ground level, objects cause winds to be diverted and redirected, causing the effect of it seeming to blow in different directions. In essence, it does not. When it is (unobstructed) at sky level, it can freely travel in its chosen path and blow the clouds in whatever direction it is going. I am no cloud expert, but this is to the best of my knowledge, take care.

If you have been on holiday in a plane you may have had
a tail wind that get you to your destination quicker,last
year we had one of 160 mph.
The winds up high tend to be of a lot higher speeds
How fast or the fastest speed of winds i don`t know
As others say they don`t have obstructions to disapate wind speed in the stratosphere so they just keep picking up strength.

Because the winds higher up are moving seperately from the winds at ground level.

The speed of light is a constant for an observer in every reference frame. That is the basic idea behind the (special) theory of relativity. Since that is the (axiomatic) starting point also for the general theory of relativity (which is a theory of gravitation), of course all calculations to determine the speed of light for an observer in another reference frame will always end up restoring the "input": The speed of light is a constant in every reference frame. In that case it is an circular reasoning: c =const. => lots of mathematical gymnastics => c = const. (when done right) So, to try to show that the speed of light is not a constant, using the theory of relativity (and gravitation is a relativistic effect) is a useless effort. In fact, if you find that the speed of light is *not* constant, is a positive proof that you made some mistakes in your calculations, most likely mixed up some reference frames. Don't worry, that also happens to expeirenced physicist from time to time.

Because up where the clouds are, there are no buildings or land masses to divert the wind around, like there is for you standing on the ground.

Because the winds are up in whats known as the jet stream.

Its very much like in a deep river. There are several "undercurrents" that are swirling and going different directions.

maybe because they are higher up and not affected as such if they were at groung level
