Newbie Rockhound - ID help? Options

[aphillips949]

Hello everyone! My husband and I just recently moved to the Grand Junction area and I was immediately taken aback by the beauty of the state, especially by the interesting geology. So, I figured rockhounding would be a good hobby to take up. I collected the following pieces on the Green River, South of Dinosaur National Monument in Utah. I *think* I may know what I have but some confirmation from those more experienced would be super helpful.

This one doesn't seem to scratch with stainless steel, and has a very fine "glitter" effect over the veining. The veining looks slightly "waxy". Is this possibly agate? Is the white/purple part the same type of stone as the red, just a different color?



I think this one may be the same material as what's in the center of the first:


I have no idea what this is. My husband seems to think it's a fossil of some sort, but I'm not sure. It doesn't appear to scratch with stainless.



Again, no idea what this one is:


I obviously have no idea what I'm looking at/for, so any help would be appreciated! Thanks in advance!
