Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
There may be as many as 25,000 artificial satellites orbiting Earth, although only around 8,300 are on record and less than 5000 are active. Our planet has only one natural satellite, the Moon.

72 + 35 (foreign) satellites were put into orbit so far (till November 2013).

With large number of low-earth-orbit satellites and the geo-synchronous orbit stuffed full of communications satellites, there aren't all THAT many "medium" altitude satellites. But there are some. The GPS navigation satellites, for example, are in highly inclined 12-hour orbits, and an unknown number of military "spy" satellites are in that middle range.
Satellites are in space not in countries.
Thousands, but the actual number is classified and varies from week to week as satellites de-orbit and new ones are launched.
It uses 66 small satellites in low earth orbit
