Teudoongie:
there's also vocalracha and danceracha (and they have songs also)
6. ddu du ddu du - BLACKPINK
7. cheer up- TWICE
vocalracha and danceracha aren't what i would consider official units, they only have like 1 song each and they aren't promoted on music shows unlike 3racha, for example. most groups have unofficial units for vocal, dance and rap anyway. but it's fine, maybe i should've been more clear :)
