But if you want some names to get started, check out the rest of JK-gumi (Kaede and Rin). If you like Iinchou for her creative/comedic moments, maybe Tamaki, Kenmochi, Gwelu or Chaika. But it really depends on what it is you actually like about her. Maybe also have a look at Sanbaka (Ange, Toko, Lize) because they seem to be somewhat popular among Hololive fans too.
