What do you want to achieve/photograph?
If you are getting the 18-200, I would not get any of these, they are basically a duplicate focal length but with less range, but slightly better quality, and the last 2 are a faster lens.
24-85 is an oldish FF lens, will give equivalent of 36-130mm on D700. Not really much faster.
17-55 is a DX lens with decent apperture
the 24-70 is (essentially) a FF equivalent of the above lens.
