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.
There are many "Medium" sized stars. For "What is a medium sized star" see related question.

There are literally billions of billions of stars. The vast majority are medium stars.
A medium-sized star is called a "main sequence star." These stars, like our sun, are in a stable phase of nuclear fusion where they primarily burn hydrogen into helium in their cores. They are in a state of relative balance between gravity pulling inward and the energy produced by nuclear reactions pushing outward.
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".
Low and medium sized stars will end up as white dwarfs.
No, the sun is not a planet. It is a star, specifically a medium-sized main sequence star that generates energy through nuclear fusion in its core. Planets orbit stars, including our sun.
Medium temperature stars are typically white or yellow in color. These stars are classified as main sequence stars, such as our sun, and emit light at temperatures ranging from 5,000 to 8,000 Kelvin.
No. The sun is a Class G star, otherwise known as Class II or yellow dwarf. It is a medium-sized star.
After the main sequence phase, a star's fate depends on its mass. Medium-sized stars, like the Sun, expand into red giants, eventually shedding their outer layers to form a planetary nebula, leaving behind a white dwarf. Massive stars, on the other hand, undergo a more dramatic transformation, leading to supernova explosions and potentially resulting in neutron stars or black holes. This post-main sequence evolution significantly influences the chemical composition of the universe and the formation of new stars.
There is no specific name of such stars. In stellar models they are given the classification of O-type main sequence stars.
