Two things the Sun provides is heat and light.
It is possible that the Sun had a companion star, and that the two became separated due to interactions of other nearby stars.
There are two types of star that can be red. Red dwarfs are smaller than the sun. Red giants are far larger than the sun.
From Earth Venus always appears close to the Sun, so can only be seen at two times of day. These are just before the Sun rises, when it is called the Morning Star, and just after the Sun sets, when it is called the Evening Star.
A double star system consists of the two components in that system. A multiple star system consists of all the individual components in that system. A binary star or physical multiple system can be limited to the enumerated components. A broader definition could include all other material which is gravitationally bound to the system: planets, etc.
After a star is formed, its two main components are hydrogen and helium. Hydrogen is the primary fuel for nuclear fusion, which powers the star and enables it to shine, while helium is produced as a byproduct of the fusion process. Over time, as the star evolves, heavier elements may also be created through fusion in its core.
"Sun" and "star" are basically two names for the same thing. Our Sun is a star, just like the stars you see in the sky - it just looks brighter to us, since it is much closer. To learn more about what makes a star a star, read the Wikipedia article on "Star".
