Pretty much river rocks except the 3rd one and those are sometimes called simple country rocks. They all would have a mineral description. I'm guessing all are from a metamorphic formation.
 

I just recently started learning about rock and minerals. Im pretty much clueless. I got them from my back yard located in Desmoines Iowa. Theres a creek behind my house and the ground is always pretty soft and damp.
 

I was just in Des Moines a couple weeks ago. What your finding is referred as glacieal alluvium, which are rocks of many kinds transported far from the north by the glaciers of the ice age. When I driving back to Colorado I was spotting some of the much larger boulders in the fields along I80. Those they call glacieral eractics. It amazes me what all happened in the past across the state of Iowa and how the glaciers moved giant boulder like those hundreds of miles from their source.
