I am traying to sculpt but somewhere I made mistake and after that my mesh looks like a bit strange in polygroup mode. Can someone tell me where I went wrong? And how can I fix it in ZBrush?

It looks like you had a polygroup selected and then hit the divide button by accident.
Hope this helps.
Actually it looks like it was re-meshed I think… right?
