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".
"Dwarf stars". Yes, that is rather confusing.
Some main sequence stars are quite big, but there are also the red dwarf stars on the main sequence.
The Sun is sometimes called a yellow dwarf star.
"White dwarfs" are not on the main sequence
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of stars are main sequence stars. They are also called dwarf stars and are medium sized stars.
A+ answer: medium sized
Fred? Actually, "main sequence," though a little long is perfectly good. For years, I felt a little ashamed of the Sun for being a "dwarf" star, but it's actually bigger than almost 85% of them. We're just more aware of the bigger stars because, well, they're so big.
Still, it does seem that there ought to be something between "dwarf" and "subgiant." How about "regular" star, or "hero" star?
I am not quire sure what you mean with "important"; the main characteristic of the main sequence is that those stars get their energy by burning protium, converting it into helium-4. That's the great majority of stars. Once they start burning helium (converting it into metals), they leave the main sequence.
The defining characteristic of a main sequence star burns hydrogen to helium in its core.
Main sequence stars are also called dwarf stars. They appear to e unchanging for long periods of time. Star clusters that are rich in stars just off the main sequence are called red giants.
The name of the main sequence star is Sun.
Our Sun is a main sequence star, as too are most of the stars you can see. There are exceptions, Betelgeuse, Antares are a few but the majority are Main Sequence Stars.

The Hertzsprung-Russell diagram is a scatter graph of stars in which a star's luminosity (brightness) is plotted against its colour (temperature). Stars are not distributed all over this chart. A majority of stars lie on or near the diagonal which goes from top left (hot and bright) to bottom left (cooler and less bright). These are the main sequence stars.There are also white dwarfs which are below the main sequence whereas stars which are giants and super giants lie in the region above the main sequence.
Some examples of star types that are not part of the Main Sequence are:Red Giants, Blue Giants, Brown Dwarfs, and White Dwarfs.When stars are plotted on a chart that compares their Temperature (color) to their Brightness (Luminosity), most of them fall into a diagonal line across the chart.That chart is known as a Hertzsprung-Russell diagram and the diagonal line on it is called the Main Sequence of stars.Stars on the Main Sequence fit this pattern because they are in balance between collapse and expansion. Their gravity that is trying to collapse them is in balance with their nuclear fusion that is trying to expand them.A difference to notice between Main Sequence stars and other stars is:Main Sequence stars are dimmer if they are cooler and brighter if they are hotter.Giant stars are brighter whether they are hot or cool.Dwarf stars are dimmer whether they are hot or cool.
Main-sequence stars; those are stars that are in a certain area in the H-R diagram. They are also the stars which burn (fuse) hydrogen-1, converting it into helium-4.
This is not necessarily true. most of the time stars with a larger diameter have more mass but some stars with a smaller diameter are more dense and have a greater mass. Find a main sequence star chart and you can compare the data.
There is no specific name of such stars. In stellar models they are given the classification of O-type main sequence stars.

Beacuse they are dimmer, but they're also bigger than the main sequence stars.
Most stars are on the main sequence; that includes red dwarves. Specifically, in this case, the closest known star - Proxima Centauri - is also the closest main-sequence star.

The 'main sequence' which is also a fusion of hydrogen atoms in the atmosphere.

Because a star on the main sequence is only fusing hydrogen. A star uses other fuels and can also shine because of residual heat. See related question
Wikipedia lists it as a main sequence star. That means that it still has significant amounts of hydrogen. Main sequence stars also typically have a smaller amount of helium (remember, the hydrogen gradually converts to helium), and even smaller amounts of the so-called "metals" (i.e., all other elements).
