Yes, it is very normal. Depending on the type of loans you had, you may have had two or three loans just in one year and the loans often change hands between lenders. If you never consolidated them, they will all show as separate loans and will issue separate interest paid statements (1098E).
If you have interest paid for all the loans, then you can either total the amount and enter as one item per lender or you can enter them all separately.
