As suggested, simply put your five frames in a 10-frame hive. When you do that, I assume the queen is already laying, so you ought to start feeding. Unless you have comb for those other five frames, the bees will need help in making wax to draw them out. When using foundation, I personally feed until all the brood comb is drawn out, 20 frames in 2 deeps...or 30 frames in 3 mediums.
My experience has been if I feed heavily until the bees have drawn out all their brood comb, and stop when they're ready for extracting supers, I get a honey crop the first season. I do not use queen excluders, and always leave the first super above the brood nest for their winter stores. The queen also usually makes it up there and lays a few eggs in that super also, but moves down as the honey flow develops. That helps prevent getting syrup in my extracted honey.
