So, my questions is, does it hurt to have many credit cards as long as you pay them off in time?
No, it doesn't usually hurt to have too many credit cards. There's a lot that goes into your credit score, and I don't pretend to know it all. However, I do know these things that lower your score:
(1) late payments
(2) recent credit card applications
(3) too high utilization of a card (you have a balance greater than 50% of your limit)
So when you apply for credit cards your score will go down because of the recent inquiry. The score then recovers as those inquiries fall off the report over time. If you pay your cards on time, and don't carry a high balance (relative to your limit), it doesn't hurt to have a lot of cards. I have 6 or 7, and my wife another few. I know people that have in the 10-20 range and more, and have excellent credit.
Now, it is possible that you can get in trouble having too many cards. You'll know it if a lender says that you have too many accounts open, which basically means at your income you can't afford the sum of all your credit limits (if you maxed out all your cards, it would be more than you could pay back). But unless a lender says that, you're probably fine.
One thing that raises your score is a decreased average age of accounts. So keep your oldest cards open, it raises that average age. Another way applying for new cards can bring down your score a bit is by lowering the average account age. But that recovers over time and increases as long as you don't close your oldest cards.
The general rule is to apply for cards very close together in time, either the same day or even the same hour, so that the inquiry from one doesn't affect your application for the other one. So if you're looking at a few cards it's best to apply all at once.
