I was combing my daughters hair and l accidentally scratched her on the nose did I just give my daughter hiv?

No. Please forgive me. You are old enough to be a mother. You have a duty to both yourself and your daughter to become scientifically and medically literate. HIV is transmitted only in certain well-defined ways and only from folks who are HIV positive. Please learn the basics so you can be a competent mother not held back be baseless fear.
