Like for example when I’m listening to an orchestra I can hear a clarinet and a violin quite distinctly from one another, but they’re both sounds vibrating through the same air. Logically, shouldn’t one air only be able to carry one frequency (Vibrate in only one way)? How does the air contain so many frequencies simultaneously?

It is because of superposition of waves.
Imagine the following scenario, you are on a swing and swinging, you will moving in an arc
Now you start standing and sitting while you are swinging, what kind of motion is that? Up down, an arc or mixture of both?
Now imagine that someone is rotating the swing and now you are also spinning? What are you doing? swinging, going up and down or rotating?
The answer is, you are doing a mix of all these, and this is called superposition.
Now imagine that someone is rotating the swing and now you are also spinning. What are you doing? swinging, going up and down, or rotating?
The first instrument vibrates the air from a stand-still position, the second instrument vibrates the air on top of the first’s vibration, third will vibrate the air on the resultant of first 2 instruments, and so on.
No add wind to the mix, will move all of this vibration along the wind direction.
Look up standing waves on YT.
