I cant be positive about which lenses some of those are from that description, especially the 55mm Rokkor X but if you were thinning I would suggest keep the 1.4, ditch the f2 lens with the XGM. i assume that is a 1:2 lens not a 1:1.2 by the way
people do get confused with that.
The others I would keep a 1.7 either the one with the aperture lock on or the version immediately before it.
Camerawise I would keep the X700, as it was such a late camera spares are plentiful and most canera techs can repair them. The XGM is a liability. When the run they are sweet but they seem prone to a lot of fails possibly be ause they were quite an early electronics based box.
