Those are fossilized crinoids, sea lillies. They are individual organism where corals are colonies.

I believe I found a few good pieces of agate with strong free standing structures. Not sure how to use this site yet...or how to upload photos...?

First rock looks like they(crinoids) are silicified or in chert. Does the rock ring when you tap it with a hammer ? I would in a heartbeat,at least saw a small corner to see if you get this:  |
