First, double check with your financial aid office to make sure that you're not eligible for subsidized Stafford loans.
I had subsidized, unsubsidized, and private loans every year. I ended up with one trade line each year for each of the three. At the end of three years, I had 9 separate loans reporting. I think the only way you'll have a new loan for each semester is if at some point you don't go for a semester, or you take some summer classes. If you just do the regular three years, then I think (based on my own experience), you'll have a separate line for each loan. I used Access Group. This may be company dependent.
As the loan is in deferment for the time being, it might not report for some time, maybe not until there's some action on the loan like capitalizing the interest. I would just call the loan company and find out what their plan/policy is.
