Rock/Fossil ID help please - 5 rocks

I've been a rock nut all my life and have a decent collection of interesting stuff. I've always wondered how I could find out more about some of the rocks I have, but never thought of looking for a rock forum! *face palm* I'm very glad to find this place.

I have five rocks in particular that I'd like to find out more about. There are descriptions on the photos: https://plus.google.com/photos/102576239827815564660/albums/6060420384731865345?authkey=CJjpwfTIiuPmAw
