Answer

"Happy birthday to you, John" is perfectly acceptable and you should use the comma.

"Happy birthday, John" works, too, but it should have a comma, as well.

Answer

It would be more usual to say simply 'Happy birthday, John'.

The phrase 'Happy birthday to you' is the first line (and also the second and fourth lines) of the song which is sung to celebrate someone's birthday. It isn't usually said to people.

Answer

better to write:

Happy Birthday John!
