Nice plant there.
re #1. I'm not much use on the id. Might be Haworthia, or a cross involving Haworthia and an Aloe. There are probably other possibilities. I think someone here will be better at identifying it.
re #2. I tend to think of brown tips like that as a historical record of the life of the plant. They are an indication that at some point it got too dry, too wet, too cold or some other event and the result were the brown tips. It appears to be recovered and, specifically, I think this is relatively normal for most growers. It's a record of a time when conditions weren't optimal for it. Just a chapter in the process of living.
re #3. Yes. It's likely each one of those offsets could be it's own individual rosette or plant until they in turn produced their own offsets. It's a vegetative process for reproducing new plants. How many containers do you want? You end up with a lot just from this plant
. Your choice. If you decide to do it. Ask here and folks can give you really good advice on the steps to take to make it successful and productive.
