1. Some friends went downtown to see the latest movies. tell me is some a noun, pronoun, or adjective
Keep in mind that not all adverbs end in -ly and not all words that end in -ly are adverbs.

In that first sentence, "quite" is the adverb.

In the second sentence, "some" is a pronoun form being used as an adjective -- a pronominal adjective, as it's called.
