Maintenance against crpc 125 against family violence

My wife has filed maintenance case under sec 125 under family violence against myself, my brother , mother ,my senior citizens father . 1) How case can be filed against my family members when im alive? 2) Also when my brother is staying separate with his wife in different city ,and my parents (senior citizens- pensioner) staying separate in different place and myself also staying separate at different city then how maintenance can be asked from all of us? 3) As per my knowledge under this section maintenance can only be filed against husband with whom she's staying? 4) if so how to remove my family members name from case.Is it possible? 5) Also my self and family members many a times called her to came back by talking to her ,her parents ,her realatives ,her father freind but she and her parents refuses to come ,send her and saying that I'm afraid that you all will kill me . I will only come if you all give me writing that if anything happens to me while staying with you ,your self and your family members will be responsible for it. Is it required to give in writing ,as per Hindu marriage act husband is responsible for all good and bad about her then why in writing? 6) my wife and her family clearly told my relatives that she will not come and stay but also will not give divorce but will take your family members jobs as all are govt employees . I will harass you and your family .But if you gave me 25 lakh I will give you divorce. 7) She had made false allegations against myself and my family members that we are beating her and try to kill her and always asking for dowary .All allegations are false . How to proove that we are not beating her nor trying to kill her. 8) my wife is staying with her father. Her father has huge property than us . He has two houses from which he's getting rent . He also has a plot located in well developed area Infront of Enggeneering college. Also he is working for a private company and his is salary is equal to my salary . Beside these he also has other source of income. His total monthly income is greater that the total income of mine, my brother and my father's pension.His elder son is married and working for company. His other son has completed Engineering also my wife has also done engineering before marriage .All were staying under one house .my wife was house wife that time but trying for jobs after marriage . Presently she is not working. So my question is if her father /family is financially sound then how she can asked maintenance under sec125 ? 9) As per my knowledge case can filed in that district place were she use to stay with her husband or last place of her stay but she filled a case were she's staying with her parents which is neither of the said place. So can I can ask for cancellations of these case against point no 9 ,8,3,4,2,1?? Also guide me on transfer of court case from her parents place to my parents place as they are senior citizen and their have health issues.
