Teeth are the same in all the smiling pics, nose looks the same in all but the first (angle and lighting make it hard to tell) and the top right (glasses make it hard to tell). Ears look the same in all of them, and the his insane franken brow looks the same in all of them but can't tell with the glasses pic. I think it's the same dude in all these pictures. Another thing of note, the gray patches in his beard are consistent as well.
The only difference in his (last pic) appearance from all the others to me is his beard and mustache are fuller and his face appears fuller, like he gained some weight.
