Adv of manner, adv of time, adv of place, adv of frequency, etc..those are the kinds of "adverbs", aren't? So How many "adv" do I must know? 

I'm not sure exactly what you mean by "different kinds", but most adverbs will end with "-ly", such as "quickly, quietly, happily, slowly". These are modified from their adjective forms: "quick, quiet, happy, slow", to describe how a verb is performed.

There are some other adverbs that are irregular and that do not use this "-ly" ending, such as "well" or "often".

This article has some good info :)
