What are some nickname ideas for me and my 3 other friends?

our names are Jessica, Jackie, Lorena and Christine. we're bestfriends and just want to have some nicknames but were stuck and cant find any. i (jess) have dimples, so thats mine. jackie is a redhead, shes HILARIOUS, and freckles. Lorena has one too. and Christine is korean, a VERY good person, and secretly funny, you think shes quiet but shes not. lol nd then we need a name like fab four but not fab, cause thats just gay. ahaha thanks!
