Can lawyer be changed when case is still going on in J &K

A Civil Case in Trial Court(sub_judge) is in progress. The respondents have submitted their arguments in form of Affidavits. In their affidavit they highlight few points like i) My land is the only passage to their house. ii) That the peice of land is recorded as Gair Mumkin raasta in revenue records I had installed an Iron Gate at the entry point of this land, which the local municipal body demolished on the request of the respondents. Currently they are being asked verbal questions in front of Sub Judge, which is being recorded. I am plaintiff. Now that I feel that my lawyer is asking vague questions, I have following queries. 1. If I hire some new lawyer, can he be allowed to ask questions to those respondents, whose statements have already been registered / recorded ? How advisable is this ? 2. On what parameters, should I judge if my current lawyer is asking appropriate questions ? Regards
