Blue I think... the hotter and bigger they are they will generally become blue or purple. When it gets old though and basically self destructs it can be red.
The largest stars are red stars which are coming to the end of their life cycle
The largest galxies have stars numbering in the tens of trillions.
the stars nearest Earth
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
Anywhere between 100 and 1,000 billion stars
No. The sun is not the biggest star in the our galaxy. Some stars that we see at night that are located far far away from other stars. One of the largest known stars, NML Cygni, is 1,650 times bigger than the sun (by radius). Our sun is tiny, compared to the bigger stars. the largest star is a billion times the sun, and by the way, nml cygni is not one of the largest known stars, it IS the largest known star
The largest class of stars are known as hypergiants. These massive stars have very high luminosities and can be hundreds of times bigger than the Sun. Examples include stars like UY Scuti and Betelgeuse.
Large stars are distributed all over our galaxy, there is no single location for them.
We can only see stars that are relatively near-by. It would be more appropriate to ask about the largest known star. Stars are known that have about 2000 times the Sun's diameter, but it isn't known for sure which of them is the largest, since there is some uncertainty in the diameters of some far-away stars.
No. Black holes are the remnants left behind when the very largest stars die.

The largest stars end their lives as black holes. These are regions in space with incredibly strong gravitational forces that can trap even light.
There are no stars ON any planet. The smallest star is MUCH larger than the largest planet.
