Question regarding Kaliyuga

I think we all know about **Kalpas i.e. Bramha years (1 Bramha day=8.64 billion years and 1 Brahma year = 3.1104 trillion human years.)** and that **we're in the 51st Kalpa as of now**. My question is that does each kalpa have a different turn of events for yugas most specifically Kaliyuga where divine intervention by God will not be as grand and usual as the other four yugas. Like for example X person was murdered on 5th November,1985 so will that same person X die in every kalpa's kaliyuga or will it be a different twist and turn of events? If a specific person Y was born on 19th December,1998 then will he be the same soul,the same body same everything in every kalpa's kaliyuga? Or someone different and all?
