False case filed

So a case was filed against my aunty who is an illiterate. Basically they accused her of taking loan amount and not repaying it. So my aunt she was just the middle person between three people (her relatives) (different place) and these money lenders who live in her town. These money lenders have been taking interest every month but there is no proof that the money was given ti them. Also, one of the money lender forged her signature. And the other two forced her to sign on the paper by threating her that they will tell her husband everything about this loan. They told her its just a witness sign and she signed. Now all these 3 have filed 6 different cases on her acusing that she has taken the money and not even paying the interest amount from the time the loan was taken. While, the truth is money was taken and given to them.( aunt relatives) and the interest amount was paid every month. They stopped paying the interest amount before 2months of the case was filed. What to do? These people who have taken the money are ready to give their statements that they had taken the money.
