a lot
Satellites are typically positioned around 22,236 miles above the Earth in a geostationary orbit.
At present there are around 24-32 satellites orbiting in medium earth orbit(11,000 miles)more the satellites more accurate navigation is produced.
there is no satellites orbiting Saturn
There are thousands of satellites in Earth's orbit, with estimates ranging from 2,200 to over 3,000 active satellites. Additionally, there are many more inactive or defunct satellites and debris in orbit.
That depends on the purpose of the satellite. Many are in "low Earth orbit", between 120 and 200 miles up. Communications satellites are generally in "geo-synchronous" orbits 23,000 miles high, and GPS satellites are in 12,000 mile orbits. And many altitudes in between.

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

There are currently 30 healthy GPS satellites in orbit.
DISH Network currently owns & leases a total of 14 satellites.
Thousands, but the actual number is classified and varies from week to week as satellites de-orbit and new ones are launched.
