How do I defrost only a few pieces of steak out of a package of 10? Can you cut through frozen steak?

I froze a package of steak (about 10-12) and I only want to defrost a couple. If I defrost all, I'd have to cook them right away. Once I defrost them, I can't put them back in the freezer right? What are my options if I don't want to cook all at once?
