Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.

voyager Explorer 1 was the first US satellite to orbit the earth. It was proceeded by two Soviet Sputnik satellites.
Circum polar satellites.
No. That only applies to low Earth orbit. Geostationary satellites orbit beyond it.
There are currently 30 healthy GPS satellites in orbit.
there is no satellites orbiting Saturn

NO! they just are up there floating around they are not large enough to have an orbit.
Communication satellites are lifted into orbit by rockets.
Yes, the satellites orbit in a geosynchronous orbit, as with most all communications satellites. (Some exceptions are satellites such as the global positioning satellites.)

a lot
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.
Thousands, but the actual number is classified and varies from week to week as satellites de-orbit and new ones are launched.
