I just removed two punchouts in a box, realized that they won't work where I need them, is the box junk or can I just use the other punchouts and leave the original ones open?

The box isn't junk. You can still use it, but I highly recommend you don't leave the holes open. Inexpensive knockout fillers are available that snap in to the holes to close them. It is a code requirement that unused holes be sealed.
