He has three fingers and a thumb on each hand. Hollow bones as well.
7, a) Which Fantastic Four villain did Spider-Man fight during his "Identity Crisis" story
Blastaar. As I remember he got the Dusk costume from the Negative Zone...or it had something to do with the NZ. He also fought, then teamed up with, kind of...I think, Paste Pot Pete, the Trapster. I'm surprised I remembered that one. It's been years, I may have this one wrong.

Er...Dusk, I think.

Evil Hyperion ruined her shit with his atomic vision.

Hornet. I'm still pissed about this.
