Arranging them in a 2 x 2 square or 3 x 2 rectangle, and using a less reflective background surface would both be good for getting more marble in better detail in the photos.
However, I jjust remembered to click on these and englarge and the detail is pretty good.
I think Akro on bottom.
And because of the seams and general patch shape, Akro on top.
The middle three look more generic. Looking athe enlarge version, I'm leaning Vitro on those but wouldn't be surprised if the top two of the three turned out to be Marble King.
