Dia Mirza: Father is a German, Mother is a West Bengal Muslim.
Dino Morea: Father is an Italian, likely from Apulia, Mother is a Christian Anglo-Indian from Kerala, so is likely half Kerala Syriac Christian and half Portuguese (Could not find specific information, my mistake if I am completely incorrect.).
Kabir Bedi: Father is a Bedi Khatri, Mother is English

Gathering information on these bollywood celebrities was difficult as not much is public, so a lot of these calculations should be taken with a grain of salt as they are most likely not super accurate.
In specific, Ranveer Singh (No Sindhi Brahmin samples exist, at least not publicly), Dino Morea (Differing sources tell differing stories about his mother's ancestry; also caste of her mother's Keralite side is unknown) and Nargis Fakhri (Fathers city of origin and caste is unknown other than that he is Punjabi and Muslim).
