A Red Dwarf is a small and relatively cool star, on the main sequence, With a spectral class of either late K or M.
They will last for billions if not trillions of years. Because of the relatively low temperatures, they are very efficient.
Any red dwarf created at the beginning of the Universe, is still in existence and will be for billions/trillions of year.
So there are no "dead red dwarfs" - yet.

What are red dwarfs and how long do they live?
A red dwarf is a small old star :)
How long can a red dwarf star live?
Due to the low rate of fusion, a red dwarf can last for tens of billion of years. Depending on the initial mass of the star, they can last from 30 -> 40 times that of our own Sun to as long as 10 trillion years for a 0.1 solar mass star.
How long do dwarf stars live?
How long stars live depends primarily on their mass. Low mass stars live longer.A yellow dwarf star like the Sun has an expected lifetime of about 10 billion years on the main sequence, followed by a "red giant" phase that is considerably shorter, followed by a "white dwarf" (Type VII) phase lasting a very, very, very long time before the star eventually cools to the point it no longer emits light in the visible range, becoming a "black dwarf".Low-mass red dwarfs (below, say, 0.25 stellar masses) could conceivably live trillions of years. We don't really know exactly what will happen to them or how long they will live, because the universe itself is only about 14 billion years old, not nearly long enough for any red dwarfs to have died.
Why the color of dwarf star is red?
Only a red dwarf star is red. Our Sun is a yellow dwarf. A red dwarf is red because it is cool, and cool colours are red whereas hot colours are white and blue.
What are the names of 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".

Can a red dwarf live longer than a white dwarf?
possibly
How long do dwarf live for?
They can live nearly or as long as other people.
How long is a red star likely to exist?
If you mean a red dwarf, then trillions of years. In fact, no red dwarf has been observed to "die".
How long is the Sun's life expectancy?
It should "live" for about 5 billion years as it is, more or less. Then it will become a red giant star. Then it becomes a white dwarf. Finally it will "die" as a black dwarf.
What do stars do in their lifetime?
they live for a long time as regular sized stars then eventually they turn into red giants and explode then turning into a white dwarf
