If the rest of the bird's feathers are fine, then the cockatiel is not unhealthy. There can be subtle differences in birds of the same species, including the length of their crest or even tail feathers. A young bird will often have a shorter crest, but it is most likely to just be the result of a slight genetic difference.
A crest may also be affected during a routine moult.

I have a cockatiel named Petie he is smart pretty and obedient and talented
It means it's frightened. A cockatiel sitting with its back to you is not usually frightened, as a frightened bird is more likely to flap and cower in a corner, keeping its eyes on you, rather than turning its back to you, which would render it vulnerable to predation. If a cockatiel sits with its back to you, it can mean the bird is distressed or ill. It can also mean the bird is, quite simply, sulking. Cockatiels bond strongly to their owners, and if a new pet is introduced, or something unusual happens in the household, a cockatiel will sometimes react in a seemingly human way - by sulking.
I don't see how you could, but if you mean by the neck, that is a very bad idea!
it could mean that he is listening to something. could also because he is sneezing.
that they are still alive and they still need heat and that they will still hatch eventually.
When a cockatiel flairs its tails and shows its wings, it means that something has frightened it. It is trying to make itself look big and threatening so that whatever it is afraid of will go away.
You're very unhealthy
No, not having a bloody nose is a good thing. Most of the time. But you aren't unhealthy!
Farting is unhealthy when you continually pass gas. It might mean that your stomach is not agreeing with you or the food you just ate.
