no they can not orbit forever. However, the time that a satellite will remain in orbit is dependent on altitude. Satellites in orbits above about 1500 miles will never decay and fall to Earth, in the expected lifetime of the solar system.
Satellites will not stay in orbit forever. How long they stay up depends on how high they are and the satellite's ballistic coefficient, or mass/frontal area. The drag from our atmosphere decreases with height. Satellites in low orbits, say 500 km, will decay in a few years. At 1000 km they will stay up perhaps a century. Above a few thousand km they would stay practically forever.
Proper disposal of spacecraft is important. A small piece of spacecraft or debris can continue to orbit for a long time, presenting a hazard to operating spacecraft.
Bodies that orbit planets or moons are called satellites.
These are called satellites. A lot of planets have natural satellites called moons, which are in orbit around the planet. An artificial satellite is one that is put there by man, it orbits the planet in a similar way.

Artificial satellites are man-made objects placed into orbit around Earth for various purposes, such as communication, navigation, weather monitoring, and scientific research. Natural satellites, on the other hand, are celestial bodies that orbit planets or dwarf planets, such as Earth's moon, which occur naturally in the universe.
Objects such as moons or satellites that revolve around a planet are typically referred to as "natural satellites" or "moons." Artificial satellites placed in orbit around a planet are simply called "satellites."
They are launched by rockets.
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.

Sputnik-I
First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.
Yes, but there are also some that orbit other planets.

Yes, artificial satellites orbit the Earth in different orbits depending on their purpose, such as communication, weather monitoring, or scientific research. These satellites are launched into space and carefully positioned to ensure stable and productive operations.
