What are the different types of dry reactions in chemistry?

What do you mean by "types"? Are you looking for examples, or for some kind of classification?

There are 3 types of reactions: Ones that water interferes with, ones that is indifferent to water, and ones that need water to work at all .

Within each are hundreds of "named" reactions.
