Yes, GPS and GeoStationary satellites are two different things.
Geostationary satellites are the ones used for GPS satellites.
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
It depends on which satellite you are talking about. However YES, it is closer than any geostationary weather satellite and it is closer than any GPS satellites.
GPS is an abbreviation of Global Positioning System, a receiving system that utilises regulated signals sent from geostationary satellites to triangulate its location upon the Earth.
Yes, generally they are.
It should be possible to have the perfectly geostationary satellites. But it is not possible. Perfectly geostationary satellite can not be made. Such satellite is pulled away by other objects like moon, sun and other planets from different directions. This force changes the velocity of the satellites.
Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
It is used for communication plates where geostationary satellites can't reach, in polar areas. Russia uses elliptical satellites where the geostationary satellites can't reach.

There are 24 satellites in the United States GPS system that are active. There are 6 more that are "asleep" and saving power until they are activated to replace one of the 24 satellites that has to be taken off line for maintenance, damage, and so forth.The Russians also have roughly that number of satellites in their GLONASS system.Europe is deploying satellites in its Galileo positioning system.Japan has or will launch its first satellite in its QTZZ positiong system.There are also about 4 satellites in WAAS, the Wide Area Augmentation System that makes GPS more accurate. Europe's version of this is EGNOS, or European Geostationary Overlay Service. It has 4 or 5 satellites.
GPS satellites do not 'find' anything, that is not their purpose.
The main type of satellites are: 1) Geostationary 2) Polar
