No, the word 'you' is not a noun; the word 'you' is a personal pronoun.
The pronoun 'you' takes the place of a noun for the person spoken to, the second person. The pronoun 'you' is both the singular and the plural form and functions as both a subject and an object in a sentence. Examples:
subject: Jane, you are a good friend.
object: Friends, I have a pleasant surprise for all of you.
