Or why do some appear to move faster than others?

Or why do some appear to move faster than others in our sky?

Do you mean in our sky? it has to do with how far away they are from earth. If you mean in absolute terms, it has to do with where they are in the galaxy, out on the edge or closer in to the center. Their proximity to other large cluster of stars, etc...

Everything in the sky is moving. Nothing is stationary. In the case of stars, they are so far away from us that their movement is not detectable to us, at least not by ordinary means. What you are probably referring to is the rotation of the earth and it's orbit around the sun. Because of that all the stars move relative to each other. If you see some stars moving faster on its own, it's probably a planet or a satelite.

Stars near the equator seem to move faster as the earth turns. Stars near the poles move slower. The North Star hardly moves at all because it is almost directly over the North Pole.
Think of the stars as being on the inside of a sphere. Now picture that sphere rotating (instead of the earth rotating). The stars near the poles have less distance to move to make one rotation so they move slower. The stars farthest from the poles (near the ecliptic) have farther to move so they seem to move faster.

If you face two objects in line 100 yards away and 110 yards away and walk to your left, the closer object will appear in front of the farther one. If you walk to your right, the farther object will appear in front of the closer one. Your changing position relative to the stars has the same effect as the earth rotates and moves you.

The stars don't actually move, we do. For example, the sun (a star) isn't really rising and setting, the earth is moving. So it looks like the sun is the one moving but in reality it is the other way around. It is the same with other stars.

i may be wrong, but they don't actually move. it's how we perceive them in relation to our place in space
