Definitely don't use sentence 1. It's a perfect example of the incorrect use of "myself" which is becoming alarmingly prevalent these days.
2 and 3 could be used but the simplest, most natural correct version is:

Happy birthday from Peter, Jane, and me.

You could also write "Peter, Jane, and I would like to wish you a very happy birthday."

You will hear people using #1, but it also annoys many others, so I would avoid it.
