Groups where all members use their birth name or all members use stage names?

Local girl group, Twice

Technically Twice don't all use their birth names. They do use their legal names though.

3YE (Birth name)

Yes I used a 3 member group so there's more chance they have it in common

Ah yes, Jihyo changes her name from Jisoo to Jihyo? So her passport would have Jihyo as her name right?

NiziU all use their birth names.

(G)I-DLE also do, if you count Minnie as a shortened version of her real name.

Jihyo's was changed shortly before Sixteen.

But Jeongyeon's was changed where she was very young (still a child) before ever joining JYPE.

The current members of Brave Girls all use their birth names, right?

Wonder Girls. All of the members goes by their birth name

I would say most Produce groups too. I.O.I might be the only exception because Chung Ha changed her name legally to Chung Ha
