"Все добре."

Translation: Everything is fine.

[notmadyet]

Can "добре" mean "OK" also?

How about,

"Everything is OK?"

[deniko]

I'd agree that's a valid meaning and your translation Everything is OK = Все добре is good

[JERINTHON]

Can "All rigth" a answer ?

[deniko]

"Everything is all right" should also be accepted
