Should I buy 5 iPhones for my family?

Okay, so I'm 13 years old and I want to buy 5 iPhones. Not for me, but for my family. Let me explain, I used to have an iPhone 4 because it was free and I had it for a few years and it only got one, tiny crack in the corner. But for my birthday, I just asked for money and I got about $400 from my moms and my dads side.So, since my iPhone 4 was available for an upgrade, I decided to get the iPhone 5 since with the upgrade, it was only $100 and I had about $300.So I got the 5 and I've had it for about 8-9 months. Now, the iPhone 5c is coming out and personally, my family really likes the new features and the look, including me.So, what I want to do is trade in my iPhone 5 to apple and get $325. I've already talked to my family and they want to trade in their iPhone 4's. They can get $110 and $135 for both of them, so we would have a total of $580. I want to get 5 iPhone 5c's for my mom, my dad, my 2 sisters and me. I have enough money for tax because I'd have $80 left over, plus I have $60 currently. Should I?

No reason they can't chip in on their own side. Since the phones you have are worth that you listed, I would make the trade and just get them on contract so most of the cost is picked up by the phone company.
