Age?

No way to tell from that one pic and that view.

I tried to attach other pics sorry new to this

Looking at the one side view we have it is hard to be sure. However, he is looking 4.5 to 5.5 to me, and I'm leaning towards 5.5.

From those pics he does not look more than 4 to me.

Really hard to tell from those pics. He could be mature.

I now see the pic of him walking away and he looks 4.5 to me in that one.
