Well, sucrose IS regular table sugar...did you mean dextrose? And I'm guessing you mean "half a pound short for a 5 gallon batch." But yeah, you can substitute different kinds of sugar, mixed or not. I've used dextrose, sucrose, and turbinado with good results. The nice thing about dextrose, is that it's superfine and easy to dissolve in cold juice. But you should have no problems swapping in 1/2 pound of table sugar.
