1. It depends on how you interpret Seraphim.

2. Even without absorbing souls, Grigori are stronger than Seraphim, as they were made to watch over and protect humans (even from other Angels).

3. Dean was filled with almost enough purified human blood to make him human, which greatly effected his powers. Also, the demon blade caused Abaddon more pain than Alastair because Alastair was a "professional" at torture, which made him more resistant to pain.

4. I have no idea. More than 1,000 is all I can accurately say.

5. Jesse's powers are enhanced when Lucifer is on Earth. He isn't the source of the Anti-Christ's powers, but he magnifies it.

6. The only powers that Sam had over demons were exorcising them and killing them. He wouldn't be able to either to Cain, no.
