Your interest rates are fairly similar and debts 1-4 are also very similar in dollar amounts. Because of this, I don't think it really matters which you choose in terms of how you pay those first four debts off. I would recommend doing whatever you feel will help you feel the most accomplished and motivated to keep going. Is it going to be saving a few dollars on interest (avalanche method) or seeing a zero balance very fast (snowball)? Once you get the first four paid off, I would take a look at debts 5-8 and reevaluate to see where your motivation is again.
