I have a decent idea on these two, want to see what others think....

Almost looks like 3 different bucks. But would guess a 4 year old and a 5 year old but hard to tell in black and white . The one int the top picture his legs look real small compared to his body so guessing 5 on that one.

What I was thinking as well, 4-5yos....Not sure about the one in 2nd pic outside feeder pen, looks 3-4 maybe.

I wouldn’t think over 5 but over 4

1.5 no more than 2.5 period

And don't make AR either, lol...

IMHO, the one standing outside the pen has a bit of a paunch on him, a thick chest, even a bit of sway to his back, at least in that one picture. I'd guess he is a good bit older than the other two.

The spindly-tined 9 point looks young to me, no more than 2 1/2.

The tall-tined buck has an awfully straight back, and not nearly the body mass as that old fella. With just that one pic, I'd put him at maybe 4 1/2. Pretty good genetics, though. I think I'd let him grow [and breed] some more.

Are these pics really from 2021?

They all look older rather than younger but not enough picture that I’d guess at a year.

Picture 234 is not a mature deer...3.5
Picture 229 Buck in the pen ...full...4.5
Buck in the background..?..can't see all of him..mature...at least 5.5

This is what I'd say, with the caveat that it's really hard to tell from one picture - esp pic 229 in the pen.
