A huge amount. As a rough comparison: Main sequence size a beach ball, white dwarf size a marble. The white dwarf, though is millions of times denser than it's main sequence parent.

Compared to the star it evolved from a white dwarf is?
Hotter and dimmer. It's much smaller, but much denser.
How would you arrange this in order red giant white dwarf and main sequence?
Main-sequence,red giant,white dwarf.
Is a white dwarf considered a main sequence star?
No, a white dwarf is not considered a main sequence star. A main sequence star is a star that is still fusing hydrogen in its core. A white dwarf is the remnant of a low to medium mass star in which fusion has stopped.
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
What one is bigger a white dwarf or a main sequence star?
Main sequence stars are bigger.

What is the size of a white dwarf compared to?
A white dwarf has the approximate diameter of a moon, or a small planet.

Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
What one is bigger a white dwarf or a main sequence star?
Main sequence stars are bigger.
Is sirius a blue super giant?
No. Sirius is a two-star system consisting of a white main sequence star and a white dwarf.
What are the smaller stars called?
A white dwarf
What is the next stage in the life of a lower-mass main-sequence star?
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
How does the surface temperature of a white dwarfs compareto a white main sequence star?
No, white dwarfs are cooler than supergiants, they also have a lower luminosity (are more faint). A different viewpoint: There's obviously a range of temperatures for these stars, but the hottest (surface temperature) known star is in fact a white dwarf. It has a surface temperature of over 200,000 degrees Celsius.
How can a star that has more mass than the sun be smaller than your sun?
The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
Is the sun a red or white dwarf?
Neither, it is a main sequence star.
