No planet contains any stars because stars are always much larger.
A solar system comprises a star (or combination of gravity bound stars) and their orbiting planets. We think the majority of stars are solar systems an we have detected planets orbiting stars other than the Sun. However in the process of forming a solar system we believe that planets my be permanently ejected from orbiting their stars and flung off into interstellar space. These planets would therefore indeed be outside any solar system.
Saturn does not have any stars. It is a planet within our solar system and does not produce its own light like stars do.
About 66 in total, though the number of star systems is less, since there can be two or more stars in any system.
There are no inherent limitations to the number of suns a solar system can have. The Koreans have discovered a planetary system with two suns. See link below.
In our solar system, Mercury and Venus are believed to have no moons.
No, Mars is a planet in our solar system, and like all planets, it does not produce its own light or have any stars. Stars are massive balls of gas that emit light and energy through nuclear fusion. Mars receives light from the Sun, which is a star located at the center of our solar system.
