Peter is likely to be in awe. He might be a bit nervous at first, but also extremely excited. He has looked up to the Avengers for a long time, so meeting them would be like a dream come true. He would probably be stuttering a bit as he tries to introduce himself and show his respect.
One way is by getting involved in Peter's school life in a more official capacity. Maybe they could arrange for some anti - bullying seminars at the school. Natasha could also train Peter in stealth and evasion techniques so that he can avoid the bullies more easily. Thor could even offer to be Peter's bodyguard for a while, at least until the bullying situation is resolved.
Well, it might start with the discovery of Ginny's pregnancy. Then the DNA test could be ordered for various reasons.

This could lead to new adventures as they try to uncover the secrets of their newly - discovered family past.
Hermione could be the main character. She's always been curious about knowledge, so she might be the one to stumble upon the idea of a DNA test in the wizarding world. She could use her intelligence to figure out how to perform the test and then discover something amazing about her own family's magical lineage.
Well, in this fanfiction, Peter Parker might meet the Avengers in a more casual setting. For example, he could be at a science expo where some of the Avengers are also present.

Peter would likely feel betrayed. He looks up to the Avengers, and for them to hurt him would shatter his trust. He might start to question his own judgment in idolizing them and could become more withdrawn.
