A lot depends on your classification.
The "Population" classification places population III stars as the least common. So rare that non have been observed, just hypothesised.
The spectral type classification puts black dwarfs as the least common, as non have yet been observed.
Of main sequence stars, O type main sequence stars are the least common, about 0.00003% of all stars.
There are a lot of "funny" stellar classifications - Methane dwarfs, Wolf Rayet stars all are rare.
The "best" answer is O type giants.
The most common stars in the cosmos are red dwarf stars.
There are 2 main reasons for this.
Firstly since red dwarfs are the lowest mass stars they are far easier to make. They are most likely the most common star to be made.
Secondly red dwarfs are far longer living than bigger stars. So many more older red dwarfs are still in the main sequence were as older bigger stars have left the main sequence to become white dwarf, neutron stars and black holes.
The most common star in the solar system is the Sun. It is a G-type main-sequence star that provides heat and light to Earth and the other planets in our solar system.
Red Dwarf Stars
The most common star category is the main sequence stars, which include stars like our Sun. Main sequence stars are in a stable phase of hydrogen fusion in their cores, which is why they are abundant in the universe.
Two stars in a binary star system are most likely 4 light years apart. Binary star systems are common in the universe and consist of two stars that orbit around a common center of mass.
Stars contain hydrogen, helium and a little iron.
The most common type of star is the red dwarf.
