The earth is a planet, not a star. An example of a star would be the sun.
It all depends on the luminousity of the star and the relative distance of the observer.
No it is a small star (about the size of Earth) that is VERY dense and quite hot (although it is not producing new energy).
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
The nearest star(s) to our sun are the Alpha Centauri group. One small star is orbiting one big star. When the large star is in front of the small star (from our view on earth) the big star, Alpha Centauri, is closest. When the small star swings in front of the big star, the small star (Beta Centauri) is closest
The sun is a medium-sized star compared to others in the universe. It is classified as a G-type main-sequence star, or more commonly known as a yellow dwarf star. Its size appears large to us because it is the closest star to Earth.

A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.
Much bigger. Earth is a relatively small planet, much smaller than even a dwarf star. A supernova is a very large star exploding.
No it is a small star (about the size of Earth) that is VERY dense and quite hot (although it is not producing new energy).
The greater a star's magnitude, the brighter it appears in the sky. Magnitude is a scale of apparent brightness as seen from Earth and says nothing about how large a star actually is or how much energy it is radiating. A small star that is closer may have a greater magnitude, as seen from Earth, than a large, active star that is much further away.
Theoretically they can be as large as a small star or as large as a galaxy

No. It is a small galaxy.
because it reflecs the earth and a large star
Relative to what?
The sun is a medium-sized star compared to others in the universe. It is classified as a G-type main-sequence star, or more commonly known as a yellow dwarf star. Its size appears large to us because it is the closest star to Earth.
