#11 and #12 are okay. You did a good job trying to make Draco the dragon less hostile but I'm not sure about the dragon. Maybe something less violent and more cute and trustworthy. The vast majority of the group leaders I'll be dealing with will be women like at church groups. Of the three remainnig, I still like your #1 better.

Looking good but please take out the slogan. It will probably change over time.
