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.
Such a system is a multiple-star system. If it contains exactly two stars then it is called a binary system.

We only have one star in our solar system, the Sun. The others are in there own solar systems. Each solar system has 1-2 stars in their system, most of the time two making them binary. Stars are made up of pressurized gases thousands of times denser then diamond, yet they are a plasma. A star needs a huge amount of gases to clump together and became nuclear, most of the time gases are used up by the end of the formation of the second star. sometimes before resulting in a Jupiter or a "dead dwarf"

Andromeda is a fairly large galaxy around 2 million light years away, it's not in our solar system or even in our galaxy. It's a huge separate group of billions of stars, each of which may have solar systems and planets of their own.
