I haven't hatched enough chicks to help you with the egg with blood coming out, sorry about that.
But as far as the chick that has hatched - it can take up to 24 hours to dry in the incubator. Patience! Just leave the chick in there, it will be fine.
As far as the chick bumping around the other eggs, that is okay too. He/she is telling the others, "Hey, its fun out here, come out and play!" Now, if he REALLY gets going and starts cracking the eggs into each other then that's a different story. But if he is just stumbling into them and falling on them, well that is completely normal.
While it isn't ideal that the pipped side ended up down, it probably still is okay. In my experience, if you open the incubator to fix the egg, someone else is going to bump into it and roll it pipped side down again. Of course, if the egg is sitting on the pip (not just that the pip is down, but that the weight of the egg is on the pip... if the pip is in the right place this shouldn't happen) anyways if the egg sits on the pip then the chick can have troubles. Not likely, but it can happen.
