A star is much bigger than earth.
Much, MUCH smaller than the smallest star.
Earth is smaller than even the smallest star, not counting dead stellar remnants.

A smaller star can appear brighter from Earth (apparent magnitude) if it is much closer. The absolute magnitude (brightness compared side by side at fixed distance) can also be higher in a smaller star if it is much hotter and more massive. A smaller star can be much heavier (more dense) and hotter than a large star, especially the huge red giants nearing the end of their life (which have a very low density).
The Earth was never a star, it was always a planet from the earliest moment that it formed out of smaller objects when the solar system first coalesced out of a giant cloud of interstellar gas. Planets are not like starts. Stars are much larger and are made from very hot gas; planets are much smaller and colder, and in the case of the Earth, are made mostly of solid or liquid substances, rather than gas (although the Earth does, of course, have an atmosphere made of gas).
yes the sun is the biggest out of all planets however the sun is a star.
An apparent change in position of a star due to the movement of the Earth in it's orbit. The closer the star is there is a larger shift and the further the star is there is a smaller shift.
actually, there is no definite answer. As time goes on as a star's life, the star will gradually increase in size until it expands to maximum size. Then, the star will start to shrink smaller and smaller, so there is always a different number of earths in a star.
Much bigger. Earth is a relatively small planet, much smaller than even a dwarf star. A supernova is a very large star exploding.

The smaller stars
simply put: no a star is about the size of our sun, maybe a bit(or a lot) larger or smaller, but if it were to collide with earth, our whole planet would be... absorbed and we would all die
