ID Rocks found on beach in Chesapeake Bay?

[copaceticsativa]

I found all of these rocks on a beach off the Chesapeake Bay. They're all currently in my aquarium, so all pictures are wet. The orange rock is very bright orange in person. Sorry if my pictures aren't too well. I can't take closer up if need be.

I do see some quartz.

Does not do real well to see them thru the eyes of a fish but it appears picture 1 and possibly 2 are pegmatite feldspars and thats mostly because of coloration. The last 3 are as EU says, quartz. Nice stuff for the aquarium though.
