The collection of planets and their star (primary) are called a solar system. The planets themselves are called "exoplanets." Once we can tell they fit our definition of planet (having cleared their orbits, etc.) we would probably just refer to them as planets.
It is called the solar system. There are also systems around other stars.
Yes, planets form around stars. In order to be a planet, one of the requirements is that you have to orbit around a sun. Also, as far as physicists can tell, planets form in the dust of other stars that have already died and left their matter.
The very first astronomers merely looked at night at the stars. They noticed that almost all the stars circled the north star (Polaris) during the night (this is due to the Earth's rotation). Some of the stars seemed to be moving differently, with paths of their own, these were not stars, but were planets.
Because the stars are relatively so far away, all planets of this solar system have the same number of stars near them.
No, all stars aren't suns. A sun is a star that is at the center of a solar system. Planets rotate around the sun. Planets don't rotate around a normal star. A star can be found anywhere around the universe. That's not the case with planets. Planets have to be in a solar system and a sun has to be in the center. If this is the case with a star, then that star can be called a sun.
That doesn't make sense. There are stars, and there are planets. If you mean "planets around stars, other than the Sun", those are usually called "extrasolar planets" or "exoplanets".
If you mean the trajectory of the planets around their parent stars, it is called the orbit, and it is not a circle but an ellipse
It is called the solar system. There are also systems around other stars.
No. Stars are like suns, around which planets may orbit.
Planets orbit the sun. Stars do not.
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
A huge mass of stars and planets is called a galaxy.

Those are called "planets". The ancient Greeks distinguished "fixed stars" - which is what we nowadays simply call "stars"; and the moving stars, which in Greek is called "planets".A planet certainly looks like a star (a very bright star, in some cases), but nowadays they are not usually called "stars".
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
The term "planet" is derived from the Greek word "planetes," which means "wanderer." In ancient times, planets were described as moving stars compared to the fixed stars in the sky. This is why they were called planets.
Orbit. The same goes for planets & other stars too.
