That's known as a binary star system.
It is called the solar system. There are also systems around other stars.
A binary star is a system of two stars gravitationally bound together that are constantly orbiting each other.
Two stars that are gravitationally bound to each other are sometimes called "binary stars".
Stars found in pairs are called binary stars. Binary stars are gravitationally bound to each other and orbit around a common center of mass. There are different types of binary systems, such as visual binaries (able to be resolved with a telescope) and spectroscopic binaries (detected through Doppler shifts in their spectra).
I can't determine what you're asking about. Stars do travel; they orbit around the center of the Milky Way Galaxy.

They orbit as stars would in any other halo. It is gravity that causes everything to orbit and "spin around" Stars can also orbit around other stars called a binary orbit.
Binary Stars
Even though they travel together they are kept in the galaxy by the galaxy's gravity, which is the combined gravity of all other stars, nebulae, and other matter in the galaxy.

A pair of stars orbiting around each other are called binary stars.
No stars travel around Mars. Stars are distant celestial bodies that appear fixed in the sky due to their immense distance from our solar system. Mars, like Earth, revolves around the sun in its orbit.
A pair of stars orbiting around each other are called binary stars.
Stars travel in various ways. On the largest scale, the universe expands, and stars move away from each other. On smaller scales, stars are most often part of galaxies and they orbit the center of the galaxy, while the galaxies themselves often are in orbit around a center of gravity of a galactic cluster.
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".
