Blue Heron Bridge Critter Help

My first time at Blue Heron Bridge about a week ago. Very enjoyable, despite the Sat/Sun crowds. This was part of the Reef Photo Macro class, which I found to be very informative and helpful. Chris Parsons was a great instructor. However, I have not encountered many of the creatures so my IDs are a little rusty. Here are my guesses:

100 - tiny ass crab, no idea (but it fits in a beer bottle)
101 - Juvenile Cocoa Damselfish (but could be a Beaugregory?)
102 - Colon Goby

103 - Courting Male Hairy Blenny?

My Blenny IDs are very rusty as I have not encountered them often.

All critters ~15fsw.

After I get the gallery finished and uploaded, I will post a link. And I will post a proper review of the class.

Thanks for any help!
