SO many. I maxed out Scherazard already, and then Mefulnash and Nina because the Challenge Recruit drops them like crazy. Also got another Shaly, apart from the quest to get her.

Apart from Ring Recruits, I've also gotten Hajad (5*), Nazuna (4*), Angelica (4*), Rebecca (4*), Sakon (4*), Ibuki (4*), Elemia (4*) and I believe Lucrezia (5*).

As the Challenge Recruit box says, "Boost to ring character drop rates!". I believe it implies not just ring characters, but arcana that are worth plenty of fortune rings, like Rare, Super Rare and Ultra Rare arcana. So it's not improbable to draw other 5* arcana apart from ring recruits.
