I am not sure what you are asking, since you have filled out the answers to the best of your knowledge but here are the answers.

1. The answer is A(adverb), an adjective is describing something like that girl look pretty and in this sentence no one/thing was being described

2. A is the answer again(adverb), same thing as before nothing was being described.

3. A is the answer, its an adverb. The boy is not being described and neither is the dance.

Edit: adding 4 and 5

4. Adjective, we are describing something

5. Adjective again

Hope this helped. If it was helpful it would mean a lot to mark as brainliest.
