Yes, it isn't clear if Raghav dies or not but Tanya saying goodbye and posing with VJ at the end gives me hope that Vj's stint is over.
I don't care if they keep Raghav as long as they replace VJ and the blast will give them an excuse but I don't think they'll do that. Chakor keeps referring to herself as Chakor Rajvanshi, that's part of Chakor's brand and will never change.
The theme of the show is still the same since the leap, it's about Anjor and Chakor's story.
I like Bini's comment if Chakor sacrifices herself to save Anjor then it'll come back full circle.
