Not enough close-up antler detail in any of the pics for me to say the larger is the same buck (top pics vs. bottom pics), but I think he's the same one, and he seems to be running with the same younger buck (topmost & bottommost pics).
That said, his rack doesn't look to have as much mass in those bottom pics, and I'm going to back-track and say he could be as young as 3 1/2 now (that based both on more body profile pics and the mass being less than normal for most 4 1/2's). Often, this time of year, very healthy 3 1/2's will have a body profile more indicative of 4 1/2 (and 2 1/2's can look like 3 1/2's).
Scorewise, my guess is a bit of a wild one here, but believe he'll gross somewhere in the 125-130 range. The short brows cost him on score, whereas long brows could easily add another 5 - 10" to whatever his score without them. His most outstanding feature to me is the width.
If you get more pics in the next week or so, better guesses can be made.
