A dwarf star could form in different ways depending on what kind. Red dwarfs and brown dwarfs are formed when nebula compresses into a giant burning ball of gas, just like most stars do; white dwarfs are formed after a star became a red giant and blown off its outer layers, the remaining core became a white dwarf; black dwarfs are formed after white dwarfs cooled down and stopped emitting visible light.
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
No a white dwarf is a small compact star.

a white dwarf
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
a white dwarf
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.
If it is small and cool enough it could be a "brown dwarf". If it is a little warmer it is called a "Red Dwarf".
the sun is NOT a dwarf star, it is a g-type star. a dwarf is a s-type starThe Sun is a G2V star G2 means the second hottest of the yellow G class and V (the Roman numeral five) identifies the Sun as a main sequence DWARF STAR (so yes it is a dwarf star) A star with spectral S is a late-type giant star (similar to class K5-M).
No, Pluto is a dwarf planet in our solar system, not a white dwarf star. White dwarfs are remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed. Pluto is too small to undergo nuclear fusion and become a star.
