Your 4/0.14 may be useful for macrophotography, but it may require a compensating eyepiece to produce good image.
Other objectives are too powerful macro subjects.
Your 100/1.25 may not be a planapo (it NA is unusually low for a planapo from that Zeiss series), does it say "planapo" on it?
You can stand your 40/0.95, tip down, on a transmission dissenting macroscope (using light from beneath), look from its back lens, and try to focus onto its internal lenses. You can see delamination better than way (it will look like photos #8 and #9 of my eBay listing of a delaminated Zeiss 63/1.4:https://m.ebay.com/itm/Carl-Zeiss-plana ... 3095868891
) . If it is delaminated, you may not be able to get $60 from it.
Maybe better to part it out and sell it. Or trade it.
