So I'm a bit confused by all these licenses

You guys have like eight different licenses on this website, and it's a bit confusing for me. I need some art to make my game with, and from what I've seen so far the LPC stuff has the highest quality when it comes to 2D spritework. Most of the stuff tagged LPC is under the CC and GPL licenses. Does that mean it's free for commercial use?
