The diagonal pattern on an H-R diagram where most stars lie is called the main sequence. This is where stars are fusing hydrogen into helium in their cores, representing the stable phase of a star's life cycle. The main sequence is a fundamental feature of stellar evolution and provides insight into a star's mass, luminosity, and temperature.
yes
The temperature of main sequence stars can vary quite a bit.

The lower right part of the main sequence in the Hertzsprung-Russell diagram contains the stars that took the longest to reach the main sequence. These stars are low mass and cool, so they undergo a longer contraction phase before they start fusing hydrogen in their cores and settle onto the main sequence.
There is no specific name of such stars. In stellar models they are given the classification of O-type main sequence stars.

No. Main sequence stars are simply stars that are fusing hydrogen into helium and have a specific relationship between color and luminosity. They range from red dwarfs to large O-type main sequence stars.
In the HR-diagram, a diagram of color vs. luminosity, most stars are concentrated close to one curve, called the "main sequence". It turns out that stars on the main sequence are the stars that mainly get their energy by converting hydrogen into helium.
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.
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".
"main sequence" is the tern.
With red giants and main sequence stars they are not entirely featureless, therefore there is no name for them.
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.
