Can same case run in high court and family court

Sir i am residing in Telangana state I got married in 2009 . she is B.Com graduate and did some traveling and tourism diploma course and used to work in deccan airways before marriage.She left that job before marriage itself. in 2010 my wife filed 498A on me and my parents & sister, DVC , MAINTENANCE CASES against me , i lodged DIVORCE, they lodged Restitution of Conjugal Rights, so main problem is with Maint. case. in 2016 the family court ordered me to pay for both wife and daughter a sum of Rs 9000 p.m and from the time of lodging case i.e. from 2010. at the time of order my take home salary was Rs 10,500 pm only. so i went to high court they gave interim stay order of 4,500 p.m from the same period, along with arrears with six installments and to put aside the case till final judgement is given. The tragic thing is where i was working that factory been under shut since 2014, we haven’t been paid anything till date. It is being reopened shortly. So I couldn’t follow their order but for that also we are applying petition as there is not much income, but mean time I was paying her what I can afford by dong some private works. The thing is that I got summons from family court against their 9000/- judgment last year. I said that case is in high court and submitted its interim/stay order copy but the family court is not considering it and compelling me to pay whole money. I asked my old lawyer to come and say that, but it is also of no use. In DVC also the lower court ordered 10000/- pm along with arrears. My lawyer went and lodged against DVC in district court and didn’t follow it so there it lapsed. When asked my lawyer he said he got confused with another case. Of-course I am again trying to face that in high court. It is in process. I am not able to understand what is going on. Single person earning a limited amount and has to pay for two cases. During that cases period my father got retired and was getting pension of Rs 1,300/- pm, and mother also not working, house wife, she used to work in private and used to make 3,500/- to 4,000/- pm) that to for 2012 only, after that she didn’t work. (didn’t understand how they ordered 9000 against take home salary 10500/- in Maintenance and 10,000/- in DVC that means total 19,500/- from 10,500/-) Please clarify in Maintenance case. When that case is in high court how that case can again be taken in family court/sessions court. How to get out of it and fight in high court itself?
