Hey RocketDawg - Sorry for the delayed response. Sure, first I'd like to say that I think many of these images contain pieces of manufactured or artificial items, so I try to look for things that have sharp edges, angles, symmetry or are cylindrical, etc, etc, etc., and look odd or out of place. I'll do my best to explain them.
1st image: Straight edges on left, top, right with 45 degree angles on left/right sides. It's hard to tell the depth of the item but it looks similar to a metal plate with some kind of design on front of it. It's also odd sticking out of the "rock" too. But I could be completely wrong.
2nd image: I find it a very odd shape with pointed front and on the bottom left hand corner it seems to have some symmetry with curves going inward. There is also a curve on the right hand bottom side of the item. The layers of the item itself seem strange too.
3rd image: The left circled item is hard to discern what it really is but to me seems to have symmetrical features on both right and left sides of it. The right circled item seems to be sticking out of the ground on a (for a lack of better word) stem with a strange top and seems to have a shadow right below it on the ground. The bottom circled item is probably the most interesting item and has a lot of weird details to it especially the thing sticking off the top of it.
4th image: I don't know what those items are, but I would bet they aren't rocks. They just have a lot of strange details to them with overlapping pieces, curves, rounded edges, wavy edges, etc. To me it looks like a remnant of a part (mechanical maybe) and we are seeing the chambers inside the item, kind of like a cross section.
5th image: pretty much the same description as the 4th image above with other items laying around it.
6th image: Here's another view of the item (bottom right circled item) from Sol 1662...
7th image: the item seems to have a rounded piece on top with a circle inside it (opened)
I hope this helps.
