HELP!!...What are these rocks?

[Fhoosa]

I've had these rocks for awhile and would love to know what they are. The orange one was found in Fresno, CA a couple of weeks ago. The non-green one was found in Australia, I believe and the greenish one was found in Northern California. I'm hoping someone can help solve the mystery of the unknown rocks. I'm new to this site so if you require more info or perhaps better photos, just let me know. Thank you in advance to all that help.

Just wondering if you have tried looking at the red/orange pieces with a black light?
