The only universal one is Christ is Risen! Truly He is Risen!
Christ is Born! Glorify Him! is a traditional greeting but it has fallen out of use in some places, unfortunately. Me being a pushy convert, I of course use it extensively trying to recharge it
I am not a fan of the many pseudo greetings that have come up like "Christ is Ascended! From Earth to Heaven!" The reason being that it can become absurd or just look weird or deliberately different.
Perhaps, however, these other greetings are popular in some local setting so perhaps anyone posting the other ones could specify where they are popular.
