hi how are you?

Helloo!

Hello, It's me...I know that you do not know me but still hiiiii!

good

hi:) I'm good, how are you?

Hi how are you?

First thing wrong with that: it should be written as, Hi, how are you? We are given commas for a reason...

Second thing wrong with that: That question is an opinion, you do not care wether we are good or not. And to some people ones terrible day, may be another's great day.
