Impossible to answer because they are dim stars so we can only see the close ones.
A red dwarf is located at the bottom right of the H-R Diagram. The stars located in that region of the diagrams are small, dim, and red.
Like all main sequence stars, a red dwarf is powered by the fusion of hydrogen into helium.
Red stars are the coolest of the stars.However, for completeness:A brown dwarf is cooler.A white dwarf can be the hottest and one of the coolest (Depending on age)A black dwarf is the coldest.
Red Dwarf Stars
Red Dwarf stars. Massive stars are also quite common, but stars like that (e.g. R136a1) don't last very long.
There are many red dwarf stars in the universe. They are not most common type of star.

Red dwarf stars are the commonest stars, at least in the region of space around our Sun.
The Milky Way has somewhere between 100 and 400 billion stars; most of those are red dwarf stars.
No, they are mostly red dwarf stars.
There are billions of red dwarf stars. I will name just one and it's the nearest star (apart from the Sun). That red dwarf star is the famous "Proxima Centauri".
Yes there are a few more [See related link for more information].--- Main sequence stars -----Red dwarf Yellow dwarfBlue dwarf (hypothetical)--- Degenerate stars --------White dwarf Black dwarf (hypothetical)--- Sub stellar stars -------Brown dwarf.
Basically, none. Red dwarf stars have a lifetime that is much larger than the age of the Universe.Actually, if a lot of additional mass falls on a red dwarf star, it would start to burn more quickly. But then, of course, it would no longer be a red dwarf star.
Because dwarf stars aren't very bright. They are too SMALL to be especially bright, for one thing.
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
they are quite smalls
