Your theory about Daya is logical in a way as the children in orphanages can considered as Siblings.
Speaking about DCP, he was introduced first in the episode FACE OFF (The same episode in which ACP shot his subordinate Daksh) as DIG Shamsher Chitrole. Earlier the role of DCP was done by the Actor Surendra Pal, but after arrival of DIG Shamsher Chitrole, he introduced ACP Prithviraj to replace Pradhyuman as the latter was considered as a traitor. In the episode when Chitrole carried out the investigation, then DCP was standing silent as Chitrole is senior.
It was later exposed by the investigation that Daksh was the real traitor and he was helping Nakul in his unlawful activities and before joining CID Daksh was working in London and not in USA. Nakul joined CID to find out his brother's murderers, but in a later episode, it was revealed that his brother is not dead but became paralysed due to drug consumption (If my memory is right as I watched this episode several years back)
