you can check sultan ka kho in rwp but peshawer would be best for these parts... I've an idea of prices for some of these;
1) 10k-12k for 4 doors without operative electric windows (don't know price of elec windows)
2) 4k-5k for both bumpers
3) 2k to 5k (depends on condition and repairs done) I would prefer getting a new taiwani bonnet in 6k as used ones are mostly built and don't get proper fittings;
5) No idea
7) No idea
btw, why you need complete used exterior... got a chassi to work on?
