Help! Autograph ID

I worked at the Capitals Iceplex in 2011 and got 15 of the Caps to sign my jersey (plus Joe B signed the sleeve and Ovi signed a different jersey). But I haven't till recently tried to ID them all. I got all but 4 of them done. Can you guys please help me with the last 4 plus can you confirm if the 4th pic is Backstrom.

Thanks!
