Is the NAACP an h1b cap-exempt employer ?

No, I don't think so. Unless they meet this definition: "an institution of higher education or a RELATED or AFFILIATED nonprofit entity"

What will be the chance for getting approval on F1 Visa?

Ask AVVO to remove the personal information from your message. Your chances of getting an F-1 are not good. Talk to an immigration lawyer.

I'm an F-1 student in a Master's program graduating in '22. Can I job hunt right now & change status if I get H1B sponsorship?

Yes, you can look ... but only use your BA/BS degree at this time.

No, this is not normal. Normally they mail back your check and all the forms.

This could be a problem if you 'regularly' sold online and the profit was fairly high. People can occasionally sell personal items ... but not...

Can I speed up the process if I got I-130 approval and I am currently in the USA on F1 visa?

You forgot to tell us your mother's immigration status and your nationality.

At this time, someone with DACA can not file for a greencard. Talk to your employer's lawyer.

When can we expect for USCIS processing times decrease,I am almost at year since we filed for my I-130 (my mom is a resident)?

Only notify the DSO and use the new info on future forms.
