False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
No, bright stars can have different temperatures. The color of a star typically indicates its temperature, with blue stars being hotter than red stars. Brightness is influenced by both temperature and size; a larger, cooler star could appear brighter than a hotter, smaller star.
Stars can be both cooler and brighter or hotter and dimmer than the Sun, depending on their size and age. Generally, larger and younger stars are hotter and brighter than the Sun, while smaller and older stars can be cooler and dimmer.

Bigger stars get hotter, and use up their fuel much faster than smaller stars.

Stars are smaller than the moon because they are further away. They're not actually smaller, its just because they are so far away. Stars are actually very large.
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.

The sun is hotter than red stars but cooler than blue stars,
stars are hotter than the surrounding area because the surrounding area isn't so hot.
White Dwarves and Blue giants are both hotter than Red giant stars.

No. The sun is actually hotter than Betelgeuse, but much smaller.
