you cannot get good results with 10 passes, that is possible only in exteriors. I would suggest using HD cache for secondary GI and raising light sampling multiplier to about 5 for this scene, since you are using a lot of lights.

decrease the albedo of scene materials (use darker colors for diffuse/reflect slots), or just postprocess the shit outta it.

You can also try limiting light transport to get a biased solution, that is however not a recommended practice. You can do it for example by decreasing the maximal ray depth.
