Rangiku enjoys teasing Ben, claiming he is more cute and innocent then Ichigo.
Even though shinigami and arrancars don't get along, Rangiku genuinely wanted to be Tia's friend. She managed to get the Tres Espada to open up to the lieutenant about her feelings for Ben and give her advice.

Rangiku and Yoruichi do not know each other that well, though they both teased Ben on separate occasions.
Though they haven't had much interaction, Rangiku complimented to Max of how his grandson is adorable, to which Max jokingly states that if she saw Ben as a 4-year old, she'd gush even more.
