I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
Yes, all the time. That's part of my job. But that will depend on what your job is, some people work only in the lab, and others work only at crime scenes.

I'm sorry, I really couldn't. You need to ask a pathologist. Best of luck!!
It could help if it's pulled hair, not cut, and if they were super-careful to leave no fingerprints or any other kind of possible DNA samples so that the police had no choice but to test the hairs for possible suspect DNA. It would also depend on the scene--if it's a heavily traveled bank, for instance, so there is a ton of discarded hairs, the police would hardly test them all. If they leave a tuft of hair on say, a chain-link fence used to get away, where the police couldn't help but notice it, then they'd have a better chance of making it a useful diversion.

I'm sure document examiners could do this fairly easily but I don't know exactly how. I would guess that alternative light source (like infrared or ultraviolet spectrums) could show that there is no difference between the signature and the rest of the document. Or I believe thin-layer chromatography could show that the chemical makeup is the same. A Questioned Document Examiner could tell you much more.
Sorry but I am not trained in facial recognition and I am notoriously bad with faces. My husband teases me about it all the time.I'm sorry I couldn't help!
