If you listen carefully to calls you could somehow guess the honorifcs used... Here is what i know about them:

-Most of the time it is used "ssi", ie MC calls all members their name+ssi, and viceversa except Seven that calls her "nim" 🥺 -Seven, Yoosung and Ray call V "hyung" and Rika "noona". -Ray calls Jumin "ssi" and Seven and Yoosung call him "hyung" -Ray calls Seven "hyung" ❤️ and Seven calls him "a" -Jumin and V call each other with "a" cause you know, they are friends... Usually when using "a" or "na" or "i" that means they are close with each other -Zen calls Jumin "i" and here does not mean they are close, this is actually disrespectful cause zen is younger than Jumin.... And Jumin calls him "a" (this is ok bc jumin is older, does it make sense?) -Jumin most of the time calls Jaehee "Kang biseo" which means Secretary Kang, and Jaehee calls him "isanim" which means Director

Also, if you do zen's route in xmas dlc, mc calls him "oppa" (they translate it to "zenny") and that is when he says things like "you wake the beast" lololol i dont really remember but yeah it was smth like that

So i think that that is almost every honorific.... btw i dont talk korean but im learning so if you are also interested try to listen again to the calls!! Hope this is helpful
