If you want to start to stan tripleS I recommend learning them by their subunits or watch the ssignal! Also you can learn them by the msnz units since they're divided into 4 subunits🥹
Iz*one, i know they already disbanded but i love their music and I used to listen to them even before their disbandment and the only members I can recognise are Sakura, Chaewon, Yena, jo yuri and Wonyoung
Try learning the names in their debut order and also watch badge war and variety shows! I’ve been stanning for a while and sometimes still mess up their names
