This is a great question. I would suggest only listing the languages that you'd be able to provide an example for. While it is notable that you had once learned the other languages, you do not want to give the wrong impresssion on your resume. If you make it to the interview round of the hiring process, that would be a good place to hit on the fact that you've learned more than what were listed and would be able to work off of memory, but may need a bit of guidance every now and then on those. Best of luck!
