I am assuming you are referring to s.375 of the Indian Penal Code. Under the Indian Penal Code 1860 or under any law in India, rape can only be committed by a man on a woman. Section 376 states punishment for rape and since rape cannot be committed by a woman, hence I believe that there might have been some confusion as it is not possible to charge a woman and her family u/s 376 although. Woman can be a victim under this section, but she cannot possibly be an accused.
I recommend you get some clarification as to the section she and her family is charged with.
