Answer

I agree with Nika - "До скорой встречи" is quite good. To be honest, only "Прощайте" means that you say good bye at the last time. So in this case you may say: "До скорой встречи", "Надеюсь, мы скоро увидимся", "До скорого свидания", "Надеюсь, я скоро вернусь".

Answer

Hi! You can also use the expression "До скорой встречи" which means see you soon.

Answer

Ну, двай! Увидимся!  + a heavy hearty handshake.  :)

Answer

"До свидания!" самый оптимальный и нейтральный вариант.

Answer

Your sentences are correct. But you can also just say "До свидания", what literally means "till next meeting".
