It's 4,000 k.
Yes dwarf has higher temperature
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.
Barnard's Star is a very low-mass red dwarf star.The estimated surface temperature of the red dwarf known as Barnard's Star is "only" about 3134 K, compared to our Sun's surface temperature of about 5778 K. It radiates mostly in the infrared, and is the closest detected red dwarf to Earth, about 6 light years away.
No, Proxima Centauri is not a yellow star. It is a red dwarf star, which means it has a cooler temperature and emits most of its light in the red and infrared spectrum.
Proxima centaury's surface is made of plasma because this star is a red dwarf. This red dwarf is the closest star to the solar system and has a surface temperature of about 3500 degrees Kelvin.

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.

No, the surface temperature of Betelgeuse is colder than the temperature of a white dwarf, the white dwarf is the hot core of a dead star. Also, red stars are always colder than white stars.
A newly formed white dwarf will be the hottest of the "dwarfs" - at a temperature of over 150,000 K but this will slowly cool over time. There is a possibility of a hypothetical blue dwarf, when a red dwarf exhausts it's supply of hydrogen. However, because of the slow speed of fusion of a red dwarf, the Universe is not yet old enough to have created a blue dwarf, so no measurements can be made on it's possible temperature.
A red dwarf.
