He hit me on my head.
He hit me in my face.

Q1:What are the differences between in and on?
Q2:Is it Ok to use both:

He hit me in my head.

Unfortunately, prepositions don't have very good rules. You just have to learn wht prepositions go with what words. So...your last 2 sentences are not natural (although, 'He hit me on the cheek.' is fine!)
I hope this helps.
