All appear to be male.
Females possess an ovipositor similar to katydids in the genus scudderia.
They develop the ovipositor well before maturity.

Actually, female jerusalem crickets have a tiny ovipositor that looks nothing like the one you find in katydids and other crickets.
Unfortunately, these photos are not good enough to determine sex. To my experience A and D look like juvenile females, and I bet C is a juvenile male, but it is really hard to tell from low-res photos.
The best way to sex them is by searching for small hooks located close to the cerci in adult/subadult males.
Try to get this paper, it contains some photos of said hooks and the mating process:
Weissman, D. B., Judge, K. A., Williams, S. C., Whitman, D. W., & Lee, V. F. (2008). Small-male mating advantage in a species of Jerusalem cricket (Orthoptera: Stenopelmatinae: Stenopelmatus). Journal of Orthoptera Research, 321-332.

I second Wizentrop. There appears to be a tiny ovipositor located on the specimens in A and D.

Exactly, I'm the one getting them, and I think A and D are females, C is most definitely male, and B could be either. Now I got a shot at breeding them!

Oh you're right.. I couldnt see that on my phone.
A and D ARE female. Sorry
You can generally tell the gender by looking at a dorsal habitus:

Note the shape of his genital plate.
