The first 2 pictures are the Maxwell stone at E 1438. pretty illegible I'm afraid.
3rd picture is the Tweedlie stone, Low Public 196, the right family but none of yours on it, it's a more modern stone. 4th picture is Archibald Arbuckle, he is most likely the grandson of the Archibald who was the youngest son of George & Mary Ann but, that'll be up to you to prove, if you want to. I only saw this one in the passing, so I don't know the section or number.
