Help please?

Found while walking along Portland Oregon area river bank. Did not seem natural to the rest of the stones.....

Locals would call all of them river agates, although I would have only kept the top two. All are forms of quartz and quite common in most of the Columbia River system. I am about 100 miles south of Portland and can find similar rocks on nearly every gravel bar.

Found in tributary to Columbia River, SW Washington. Heavy and nice shine when wet. Dull green when dry.
