A lot really depends on your classification of what a star is [See related question]
However, in the general terminology of a star:
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
Current observations seem to suggest that about 50% of all stars are multiple star systems
Yes, all binary stars are part of star systems. Binary stars are pairs of stars that orbit around a common center of mass due to their gravitational attraction to each other. While they may be the only two stars in their system, they are still considered part of a larger system.
Yes. Around 76% of the stars are low luminosity stars.
Stars come in a variety of colors depending on their temperature. Hotter stars appear blue or white, while cooler stars appear red or orange. There are also yellow and even green stars, but these are less common.
they all have stars.
production of light
there all made of the same thing
All of them have stars and space dust for sure.
We are all made of stardust

All of them - but mostly hydrogen & helium.

main sequence stars all are burning though fuel at asteadyrate in there cores. with the proton+proton chain our sun is a main sequence star

Starfish is a common name for what are called sea stars. As explained by the name, sea stars exist in all of Earth's oceans. No sea stars are found in freshwater environments.
No, in fact they are quite common. Many stars that, with the naked eye, look like a single star, are actually double or multiple stars.
