Answer:

"Hello, Mr. Daniels, how are you doing?" is in fact, correctly punctuated, but the way it is written is unnecessary.

It should be written/is more commonly written as, "Hello, Mr. Daniels. How are you doing?"

Explanation:

The sentence, "Hello, Doctor Williams I am one of your students," should be written as this:

"Hello, Doctor Williams. I am one of your students." But if you want it shortened, it's written like this:

"Hello, Dr. Williams. I'm one of your students."
