Samrat is bua's son of Devyani not a kaka's like Virat & Mohit.
North Indian relationship differs a lot from South Indian relationship (East(West Bengal and NE) and West Indian falls in the same category of North Indian)
In our culture, Bua, Mami, Kaka, Mausi's sons all are cousin brother, not any other relationship.
Like Virat's child will call both Samrat and Mohit Kaka.
Same with Samrat's child, will call both Virat and Mohit Kaka.
In the same way, Harini will call three of them Mama because Samrat is cousin brother of Devi.
Even if there was any Bua's son of Pulkit, Harini would have called her Kaka.
