One of the victims is said to be critical.
Three of the sisters work as teachers in school and one of them is a student. The incident happened when they were returning back home from school.
The victim whose condition is critical has been shifted to Delhi's Gangaram Hospital for treatment.
"We were coming back from work when two men came on a bike; they had their faces covered and attacked us with acid and ran away," one of the victims told journalists.
However, police is yet to identify and arrest anyone in relation to the case.
What the law says about acid attack
According to latest anti-rape bill, person involved in acid attack has to serve life imprisonment in jail.
However, human rights groups in India feel that the new changes in the anti-rape laws do not have the power to end rising numbers of acid attack on women.
Statistics say in last decade the number of women attacked with acid has grown up hugely.
New legislation has been passed following the gang rape of a student in Delhi in 2012 which has increased the punishment for acid attacks - but campaigners say the horrific nature of the crime means it needs its own specific legislation.
