I like 1,2,4,5 a lot, the content is great.
The first shot is my favourite. The mould on the foot is very apropos.
#2 (dual headstones) is a bit underexposed.
I don't find much of interest in #3 (coffin shape).
I like number four, but I think you missed the crop. The right edge of the cross is cut off but not the right. I would have liked to see the crop moved slightly right to capture both sides of the cross evenly.
