Really nitpicky list of questions

Schultz shot Candie because Candie is an asshole. He is a sore winner and thinks he's better than everyone. He is a terrible human being. Shultz couldn't stand him being alive anymore so he shot him and didn't care about the consequences.

Everyone was armed during those times. They are guests they are allowed to be armed. Once they are seen as enemies they are disarmed.

Stephen is a slave. But he has been around so long and basically handles the day to day business. Candie is the owner but Stephen operates everything and has a cushy position. He has a cane to get sympathy and so people think he's a harmless slave. Him being the head house slave is the lowest of the low morally not in terms of hierarchy.

Nitpicky in D'artangnan. Candie paid 500 hundred for 5 fights. He paid in full he expects 5 fights. Candie can't get his money back either. If you pay someone to build a house you expect it to be completed not almost done and take a prorated price.

Django pulled over Hoots horse because he was disrespecting Django. It was clearly meant to be an insult.
