Our Sun is basically an average star - nothing special about it. It's not a massive star and it's not a red dwarf, which is thankful as if it wasn't we wouldn't be around to appreciate it.
There are billions of stars that are not on the main sequence.
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.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
"main sequence" is the tern.
main sequence stars , our sun is also a main sequence star
No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.
Main sequence stars are found in all galaxies.

Main Sequence
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 main sequence stars on the Hertzsprung-Russell diagram that are least massive are the red dwarfs. These stars have low masses compared to other main sequence stars like our sun. They are cooler and fainter, making them difficult to observe compared to more massive stars.
