What is the best way to pay back loans?

I would recommend watching or googling Suz Orman. She has some great advice for working on paying back student loans as soon as you start working, versus continuously deferring them and further accumulating interest.

I would gather information about each of your loans--amount, interest rate, monthly payment amount, the website for submitting payments. Figure out if you can make the base monthly payments, which can be a struggle for many people. Look at the interest rates. It will benefit you to pay off the loans with the highest interest rates first, and it might be possible to consolidate your loans to get a lower interest rate.
