We did P&P, A Doll's House and Browning so I can't help with North and South. But here goes. Just looked up 'paradigm' in a dictionary to make sure, and the relevant meaning it gave was "a pattern or model" so I'm going with that.
In Pride and Prejudice: Religious paradigm would be Mr Collins, he's the only member of clergy that is really presented in the series (cherryblossom, while the book is a help, the text on the syllabus is Simon Langton's miniseries, not Jane Austen's novel... very important for the people who do it, not to get mixed up, lol). And Mr Collins is basically a sycophant obsessed with material possessions. Pretty funny to watch, right up to the point when you're strapping yourself to the chair so you don't take the red-hot pokers to the TV screen in the absence of Collins' *real* eyes...
Social paradigm, well, considering the different areas of society, I'd say Lady Catherine would be one, Mr and Mrs Bennet another. Darcy could be as well, but he and Lady Cathering are essentially in the same level of society.
Economic, I think, is just social, and there's no real scientific paradigm or philosophical, that I noticed anyway.
For A Doll's House, scientific paradigm would be Rank, if anyone, for reasons cherryblossom already said. No religious paradigms, no real economic paradigms, and pretty much *everyone* is a social paradigm, lol.... with the exception of Rank, the maid and the children. Philosophical may be Nora, since she deviates from the social norm and puts herself above her 'duties' to her family, which is a philosophy in a way...
Anyway, interesting question, I didn't really think about paradigms until now.
