1. It was stated that all the doors were sealed. That's why no one actually was able to use it.

3. You can see Cas' power buffer before he did it. I think he used most of his power to do something like that.

5. That's something I want to know too but it probably won't be explained.

7. I think what they meant by that is that it was only quiet in that specific part of Hell.
