Red Giants. Stars not on the main sequence
A main sequence does not do anything - it is just a name for a period in a stars life. [See related question]
"Main sequence" stars are no longer new, and are just cookin' along for millions of years. "Main sequence" stars, depending on their weight and whether they orbit another nearby star can get old and become red dwarfs, white dwarfs, black dwarfs, neutron stars, novas, or super-novas.
With red giants and main sequence stars they are not entirely featureless, therefore there is no name for them.
The name of the band where most stars are found would be called the Main Sequence.
* Blue * White * Yellow * Orange
Yes. Amsonia hubrichtii is the scientific name of a blue star. Blue stars are part of the Main Sequence stars.
A "main sequence star" is not really a type of star but a period in a stars life. When a star is in "main sequence" it is converting hydrogen into helium. It is then usually called a dwarf star. This is the longest period in a stars lifetime. Our Sun is a yellow dwarf in "main sequence".
