Did somebody want an easy puzzle giveaway?

Couldn't think of anything easier than to ask about numbers. The downside for the easiness is a relative worthlessness (if that's even a word) of a game in question. I wanted to give 5 of these at once in a single public giveaway but was cockblocked by the site system telling me I could only create 4 new giveaways since I'm new at the site. Oh well, somebody will want this game anyway.

Link to the giveaway: http://bit.ly/####### , all 7 symbols are digits.

1. Fourth prime number.
2. A component part of the number of the beast.
3. Number of black presidents of the usa.
4. Atomic number of the oxygen.
5. Number of fingers on a normal human hand.
6. Zilch, nada, nil.
7. Number of people involved in a quartet.

Fear not, those who still can't figure it out! I will be adding hints, guidebooks, solutions, FAQs, Prima Guides, gamefaq articles and wikipedia pages to help those in need!

Update:
Aaaand here's a bunch of hints.

1. Prime numbers are natural numbers which are greater than 1 and have only two divisors, 1 and the number itself.
2. This number is usually associated with devil, evil, hell and all the bad things. And it's not 13.
3. He's a combobreaker.
4. It has 2 full 's' electron levels and one 'p' level filled by two thirds.
5. Look at your hand. Now back to me. Now back at your hand. Now back to me. How many big pointy things are there on your hand?
6. If you can't find an answer for this one, it's probably cause there are none! Ha!
7. Not counting the producers, agents, sound guys, groupees, prostitutes and other fellows.
