Appeal against dismissal of name deletion applications

Dear experts,

I filed name deletion applications for 3 accused/ respondents in PWDVA case. Those applications have been dismissed by the trial court.

I want to appeal against this dismissal in the sessions court.

Do I need to file three different appeals (one for each respondent)?

Can I file one single appeal for all three respondents? Can someone help me with the procedure? What's the time limit for filing the appeal in sessions court?

Thanks!
