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.
I'm sorry to hear about your brother. Unfortunately I have no idea how much blood there should be, you'd have to ask a pathologist, but from my experience I can guess it would depend on two things--what kind of surface was he on--concrete, tile, carpet, dirt? Also, how long the heart kept pumping after the injury. I have seen gunshot victims where they barely bled at all, and others were completely soaked practically head to toe. So there are a number of factors that will affect this.
Vomit, horseradish, copper (as in pennies) and some cleaning compounds can also give a positive luminol reaction.Good luck on your project!
I have not because I am not trained in facial construction. We did have a case in which we had a reconstruction done on a skull which helped identify the person. As for the casket, I don't see why not, depending upon the skill of the wax worker.
Unlike what you see on TV, a hair and fiber expert never 'matches' hairs or fibers (except in the case of DNA analysis). We can say they are 'consistent with' having come from this person or this article of clothing in that all the microscopic characteristics are the same or within a group of the same characteristics. Though dyed hair is quite distinctive with the growth since dying and the color so it would be a strong indication that they came from the same person, you couldn't actually put a number on it (like 'there's a one in two billion chance this came from someone else', like DNA). That's largely why hair and fiber comparisons are rarely done any more.

No. There is no time stamp on DNA, so far as I know.
