Five of the women were arraigned on assault and other charges on Wednesday in Stamford Superior Court. The other woman appeared in court Monday on the same charges.
Police say the Sept. 23 attack on the 25-year-old woman from Port Chester, N.Y., happened during karaoke night at Bobby Valentine's Sports Gallery Cafe in Stamford.
Authorities say the six women, all under the legal drinking age of 21, knocked the singer to the floor, punched her and pulled her hair. The victim suffered bruises and a chipped tooth.
The victim has said she was singing "A Dios Le Pido" by Colombian superstar Juanes when the violence began.
