[Ghost in the Shell] Do cyborgs still need to eat? Sleep? Can they get pregnant?

Overall, what human necessities do cyborgs still require? What human aspects can they no longer do?

Depends on how cyborgorized you are. Motoko Kusanagi for instance does not need to eat as she's a full cyborg-"her" is just a brain in a case, she does not eat in the traditional senses. Her brain is encased in a shell what's called a braincase is supplied with nutrients and what it needs through the braincase. There are "cyborg food" that cyborgs with special stomachs can eat like regular humans. 

Cyborgs still need to sleep as they are still humans in the sense that they are a brain. Various drugs and implants can make a cyborg last longer, more alert, and need less sleep, but overuse of it is detrimental to ones health.

Overall a full cyborg can feel, smell, pretty much do anything a human can do in terms of sensation. Motoko Kusanagi is part of the military and thus has in her many military grade parts unavailable to the general public.
