Unfortunately, this is a hard question. The movies offer little about the culture, but they do allow us to make some pretty solid assumptions (and im no predator expert so others please feel free to jump in here at any time lol). We know they have a structured stratification, and it is probably a caste system based on honor and or physical prowess. We also know they are carnivores (pred 2 sucks the flesh from his trophy). Now for the rest of your questions, one would have to look into the expanded universe and this is a tricky thing for serious fans because much of it can be defenistrated. The books and comics that I have read explain that the predator females are physically stronger but the males are in charge. Reproduction is an honored thing, and is said to be very hazordous to a males health because he must overpower the female. I remember the AVP books have Dechande mentioning that he has spread his seed many times, so I do not think they have a family unit. Perhaps they are like a lions den, with one male reigning over a clan of females? And in the event of a human/pred hybrid... that is a very interesting quesiton. The comics and books claim that predators see humans, or 'soft meat', as a very dangerous enemy due to our technological warfare but this fear is also out of confusion because not many preds have faced us and come back to tell their tale. We are seen as a threat, but they also respect us. They do not try to interfere with us unless it is completely necessary, but this contradicts the movies a little so take it with a grain of salt. Anyways, the predators have allowed for a human to hunt with them (Machico Naguchi in the AVP universe) but she was not respected because she was 1) a woman on the hunt and 2) because she was different. The preds tolerated her because she was a blooded warrior, and would have killed her otherwise. This speaks highly of their dedication to tradition, but shows them as a race who holds grudges (no duh lol) So, any halfbreed would probably be tolerated as such, but be labled an outcast. My guess is that this hybrid would be treated like anyone born mentally handicapped or physically deformed before the rise of modern medicine or in a third world country. Once again this is just speculation based off of non-canon and all of it is open to debate.
