Main sequence stars include the hottest stars as well as the coolest ones.
Because there not that hot
"main sequence" is the tern.
Main sequence stars vary widely in temperature and brightness, depending on their mass. While some main sequence stars, like red dwarfs, are cool and dim, others, such as blue giants, are hot and very bright. The majority of main sequence stars, however, are found in the middle range of the spectrum, often classified as yellow or orange stars like our Sun. Thus, it is not accurate to say that main sequence stars are mostly cool and bright; they exhibit a broad range of characteristics.
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
No. All stars are hot. For stars on the main sequence, the largest it is, the hotter it is. When a star leaves the main sequence to become a giant or supergiant it will cool down, but will remain hot enough to glow brightly.
Because there not that hot
There are billions of stars that are not on the main sequence.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
No stars blue? A star's colour depends on it's temperature. A blue star must be very hot in order for it to glow blue. All stars in the main sequence sre only hot enought to glow yellow, not hot enought to glow blue.
T Tauri stars are pre-Main Sequence stars which are large but not as hot as O and B Main Sequence stars. They mainly fall in the categories of F, G, K or M, and they are not yet on the Main Sequence because they are still accreting mass and are still very young and unstable.

No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.
