Which members have higher and lower গান গাওয়া voices?

I'm sorry if i'm phrasing this wrong but I was wondering if people could tell me who has the highest voices (ex: Sunny) , lowest voices (ex: Adele), and who has a medium voice. Also, this is all for their গান গাওয়া voices, not talking. Thank আপনি and sorry for phrasing this wrong!
