The commonly used altitude classifications are Low Earth Orbit (LEO), Medium Earth Orbit (MEO) and High Earth Orbit (HEO). Low Earth orbit is any orbit below 2000 km, and Medium Earth Orbit is any orbit higher than that but still below the altitude for geosynchronous orbit at 35786 km. High Earth Orbit is any orbit higher than the altitude for geosynchronous orbit.

Yes, but it has to be travelling at the MOON'S orbital velocity, which is quite a bit more than that needed for low earth or even geosynchronous orbit. The faster one goes, the higher the orbit.
The cost varies depending on the size of the satellite, which determines which launch vehicle (rocket) can be used, the orbit the satellite is to put into (polar, low Earth orbit, geosynchronous, etc.) Costs start at about $50 million which does not include the cost of developing and building the satellite.
From Earth to an orbiting satellite it takes approximately 200 to 299million M/S or slightly slower than the speed oflight. This varies on weather and atmospheric conditions. The signal is significantly faster, or closer to the speed of light (299792458 M/S), in the Vacuum of Outer Space.
YES As height increases, speed of satellite decreases.
For any body in a closed orbit around another body, the farther apart the two bodies are, the slower the satellite moves in its orbit.. When the Space Shuttle is in "low earth orbit", it moves faster than the Moon is moving in its orbit. A satellite in an elongated orbit, that spends some of the time close to the earth and some of the time farther away, moves fastest at its lowest altitude, and slowest when it is furthest away.
This actually depends on the orbital radius, or distance from Earth's surface (or center). The further away the satellite is, the slower it travels to stay in orbit (related to Kepler's second law). A satellite that is really close to the atmosphere and barely in space needs to travel at about 7800m/s. A satellite can speed up and increase its tangential velocity to make its orbit bigger. A bigger orbit results in a lower speed. Interestingly, this means that an orbiter speeds up to slow down. Likewise, a satellite in a high orbit can fire its engines backwards to reduce its speed to get into a smaller, faster orbit, ultimately speeding up. ================================ In an orbit that's not a perfect circle, the speed in orbit is always changing. The satellite moves faster when it's closer to the Earth, and slower when it's farther out.
Geosynchronous orbit? or Low Earth Orbit?
Satellite orbit the Earth at different altitudes. A good overview of Low Earth Orbit, Medium Earth Orbit and Geostationary Orbit can be found here: http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx

It will stay with the satellite for a while, in a similar orbit. If the satellite is in low orbit, gradually the object will get away from the satellite, due to "tidal forces" from Earth.
Satellites in a low orbit, however, are slowed by friction with Earth's atmosphere.
The MIR station was in low earth orbit ( about 300 km or 200 miles) and traveled at 17,200 mph (27,700 km/hr), about the same as the space shuttle.
If a satellite is in geosynchronous orbit, it will take the satellite 24 hours, a day, to orbit the Earth once. This is so because geosynchronous orbit is when a satellite orbit the Earth at such a time, that is is over the Earth at all times.
