It looks like a 8 1/2" x 11" home printed photo the seller signed himself. Those signatures are not authentic. Not even close. I hope you didn't get ripped off for too much on that one.
Agree with the others in here. Looks like signed by same person.
I am not much into the other signatures, but as a E Street band-fan, I can say right out that Steve Van Zandt`s signature is totally off, not similar to anything he has signed on E Street Band-items. And I would be very surprised if he changes his style totally for Sopranos-items. (He wouldn't sign with Little Steven or Miami Steve of course, but the whole style and the letters are not similar at all here)
I have one by Van Zandt here from my full-band signed programme for comparison:
