Priya and Nikhil are the children of Uncle Vinod. Since Uncle Vinod is Meera's uncle (her mother's brother), Priya and Nikhil are Meera's first cousins. Raj is Meera's brother, so Priya and Nikhil are also Raj's first cousins.

Uncle Vinod is Raj's mother's brother, which makes him Raj's uncle. Therefore, it is correct to say that Raj is Uncle Vinod's nephew.
If Raj is Meera's brother, and Meera's mother's brother, Uncle Vinod, has two children, Priya and Nikhil, how are Priya and Nikhil related to Raj? Additionally, is it correct to say that Raj is Uncle Vinod's nephew? Make your response very short.
