Kokila sister Jigna daughter but Kokila ia like 80 In t he show lol

I think the matriarch of Desai family that is Anant's father is Kokila's elder brother. In that sense, Anant is Kokila's nephew and Ahem's cousin brother. Gehna is the maid of Desai family so like how others call Kokila Fui Gehna too calls the same.

And dont forget this is Saathiya 2 so there's no connection here with Saathiya 1. That story had ended and this is a fresh new story.
