Help I.D. these rocks I found

Hello.
I live in Northeast Pennsylvania, right next to abandoned strip mining property.
About two years ago I was really big into trying to find interesting rocks in the woods.
Here are the examples I found, some of them I think I know what it is, and others I'm completely lost.
I'm *pretty* sure on what these are, someone correct me if I'm wrong:

^ Iron ore that rusted away because it was exposed to oxygen? The orange wipes off, and I'm positive it's rust.


^ Both pieces of petrified wood. The bigger piece seems to just be on the surface of the rock, it doesn't extend throughout it. The smaller example I broke in half chipping it off a bigger rock. you can see the wood grain on the opposite side (one piece is flipped over).
 ^ Imprint of this one type of prehistoric plant that grew in the area...
Here are the ones I'm unsure of.
These next couple I broke out of a bigger rock if that makes sense. I honestly thought it was petrified poop or something so I had to break some of them open, and the insides contain what you see. I'd appreciate if anyone could tell me what this stuff is:




Hopefully none of the pictures are blurry, sorry for the bad lighting.

Thanks!
Don't the ones on the bottom look like turds? I literally thought I found super old dog poop that turned into rocks in a rock or something.
Someone please.

I am by no means an expert on rocks, but I'll give it a shot:
1) Yes some sort of Fe containing ore. There are several types. 2-3) Yup, petrified rock. 4) What makes you think the impression is necessarily from a plant. That looks an awful lot like scales to me, but I guess it could be from a plant maybe some sort or flower or seed pod. 5-8) I don't know what these are, but there actually is a name for petrified poop and it's pretty common. It's called coprolite, but there is some disagreement on whether or not it is actually fossilized poop unless the specimen in question clearly contains digested plant or animal remains.
Cool finds.

Honestly I thought it was fish scales or something which is why I grabbed it , but when I got home I found a PDF online with some examples of the plant life and it really looks like the same pattern from this certain fern plant that grew back in the day that had an almost palm tree like trunk to it. 
Thanks for the help. About to upload a bunch more photos of other things I've found.
EDIT: More fossil imprints from plants:

coolest example of petrified wood I've ever found, it looks like part of it has quartz in it for some reason... it was broken in half when I found it.. I'm pretty sure I found this in a powerline:

Hopefully those aren't blurry as well. I don't know if it's the camera or my shaky hands.

the orbs are concretions, and the one with the red center looks like ocre or iron. i'm not good with pennsylvania rocks, i don't think i've ever seen any before. i used to find similar concretions in western kentucky, as well as alot of crinoid fossils. i'll try and id the fossil for you. i'll just have to call that next to last one cat shit. that iron ore could be hematite or magnetite, and also looks like the ore i've found in kentucky.

Thanks for the help! From the little researching I've done, PA sucks for cool fossils.. Especially the Northeast part of the state, it was mostly underwater.
I know most of the fossils I find are seed ferns.. According to this handy common fossils of PA PDF I found online: http://www.dcnr.state.pa.us/topogeo/education/es2.pdf Page 22
Those are exactly the type of fossils I find. I'd shit myself if I ever found a trilobite...

a neighbor vendor at quartzsite sells trilobites by the flat(10-20 tiny bugs) from utah and he gets over $100 per flat wholesale. get out there and split the mudstone.

 here's a fire obsidian i finished today, well it could still use cerium oxide polish but it's good enough for me, for now at least. i like doing my cerium polish all at once in big batches for less waste and mess.
