Main sequence stars are bigger.
No, a white dwarf is generally smaller than a main sequence star because it is the remnant core of a star that has exhausted its nuclear fuel and collapsed. Main sequence stars are actively undergoing nuclear fusion and are typically larger in size.
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.
The correct order of these stellar evolutionary stages is main sequence, red giant, white dwarf. A star begins its life on the main sequence where it fuses hydrogen into helium. As it runs out of fuel, it expands into a red giant before shedding its outer layers and collapsing into a white dwarf.
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.
Sirius is not a single star but a binary star system consisting of a white main sequence star and a white dwarf.

No. Sirius is a two-star system consisting of a white main sequence star and a white dwarf.
Neither, it is a main sequence star.
Sirius is not a single star but a binary star system consisting of a white main sequence star and a white dwarf.
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
False. The sun is a yellow main sequence star.
The sun's life cycle includes the stages of formation, main-sequence, red giant, and white dwarf. It is currently in the main-sequence stage, where it fuses hydrogen into helium in its core. Eventually, it will expand into a red giant before shedding its outer layers and becoming a white dwarf.
