No satellites are known to orbit Mercury or Venus.
Jupiter is the largest planet in the solar system and as such has a tremendous gravitational well. This gravity is what has enabled Jupiter to attract and keep in orbit its 67 moons.
Yes. Any celestial body, of substantial size, in close orbit around a planet is a moon. There are trillions of planets outside of our solar system, and there are even more moons.

I assume you mean "the focus of the ellipse". That's the Earth, since the Moon revolves around Earth.
All object except the Sun orbit round the Sun. The moons also orbit round their planets.
In most cases, the moons are about as old as the planets they orbit, perhaps slightly younger. Most objects in the solar system formed when the solar system did.
No satellites are known to orbit Mercury or Venus.
Moons are approximately spherical objects which orbit planets and are smaller than the planets that they orbit, although they are still relatively large objects (so an orbiting dust particle does not qualify as a moon). Since moons orbit planets, their motion around the solar system is controlled by the planets that they orbit; planets orbit the sun, and planets take their moons with them.
