Type-O are the hottest but there are very few. Then type-B, there are more of them but still not a lot. Then you have type-A, which are very common, then F, then G like the Sun, then K and then the coolest common ones, type M which are the red stars like Betelgeuse.

What is the least luminous spectral class?
Spectral class Y, which is typical of "brown dwarf" stars.
Why are there no massive O and B stars?
There are stars with spectral classes of O & B (e.g. Rigel) R136a1 is a star of the spectral class WN5h. Wolf Rayet stars have this kind of spectral type.
Two stars of the same spectral class must have the same what?
temperature
How common are sun like stars?
Our Sun has a spectral class of G (Yellow dwarf). About 1 in 13 stars, in our solar neighbourhood are within this class
Is spectral class B in space hot or cold?
Spectral class is the categorization of stars by temperature and size, mostly the former. Spectral class B is very hot. In descending order (hottest to coolest) the spectral classes are O,B,A,F,G,K,M. You can see that B is very near the top.
