Extremely informal
A bit formal overall using complete sentences but with some less formal Maria: Oh, hello Chris. How are you doing?
Chris: I’m well. Thanks for asking. How are you?

Chris: That’s good to hear.

Stiffly formal

This one sounds like the TV character Eddie Haskell.
“[Eddie] is so polite, it’s almost un-American.”
In the US, everything has become more casual than it was in the past. In the past there were a lot more social norms when it came to personal interactions. What was the norm in the past would be called stuffy today.
“How are you?” is OK for almost any occasion from meeting someone for the first time, to job interviews, business meetings, etc.
“How ya doin’ ?” is also OK in most occasions. This may be regional, but I suspect it’s OK anywhere in the US, even for something like a job interview.
“How are you?” or “How ya doin’ ?” are too formal if you are meeting your best friend. You are more likely to say “What’s up?”, “Hey”, or no greeting at all.
A good example of how things have become more causal is the lack of titles. In the past, titles like Mr., Mrs., Miss were far more common, and even expected in many situations.
In the past, we sometimes said that two people were on “first name basis”. This meant that they knew each other well enough to use first names rather than titles.
When I grew up, I would NEVER address an adult by their first name. There was no circumstance that I would do that no matter how well I knew them. Today, it’s pretty normal for kids to address adults by their first names (with some exceptions).
