The first two that come to mind when I think of tov are the phrases tov toda and mazal tov.
It means: Thank you for all the compliments. I think you intended to say wise (chachama) instead of grumble (hama). Well, all the best and have a good day tomorrow with your students.
If you mean the Tov, it is "good". There is no such word as Tobe in Hebrew.
Maya Tov means "A good Maya". BUt I think you might be asking about Mazal Tov (מזל טוב) which means "congratulations."
Those two words, literally translated from Hebrew, would mean "good, thanks".
Chodesh Tov means "have a good month" and is the traditional greeting used on Rosh Chodesh.
hu hag tov (הוא חג טוב) means "it is a good holiday". It is a line from a Hanukkah song.
