You can use them if you want. You do not need to give credit. Sorry Wu and Zane are a bit choppy. Zane's always the hardest because in order to turn him into a sprite, I have to remove the WHITE background, and he is the WHITE Ninja. So, when I try to remove the background, I end up removing some of Zane's suit. So, I have to change the coloring a little bit. As for Wu, well, the same thing.
