per code, you are allowed 0.5% drift from wind or seismic
so if the building was 100 feet tall, you would be allowed 6 inches (in each direction) or 12 inches total
soo the Sears Tower at 1450 feet would sway 7.25 feet in each direction or 14.5 feet total
this is why elevators are staggered in tall buildings, the shaft is sized for the drift, the drift would be too great, and the cab would bang around too much

Yes, in fact they all sway in the wind. This is something that must be considered when designing such tall structures. The Sears Tower in Chicago (the windy city) sways quite a bit.

Yes, all tall buildings are designed to sway in the wind. There is a limit to how much they should sway, given by a human comfort factor, determined many years ago in some buildings that actually swayed many *feet* side-to-side near the top. Modern skyscrapers do not sway many feet. Some of them sway up to a foot, or so.

Certainly.
All tall buildings are built to "give" a little, in a wind. If they weren't, they would break apart.
