No.
You cant,you must do the companions quest in order to become a werewolf. Its the only way,however there is a way to become an alpha werewolf,which instead of being black, you are white and feared by all other werewolves.
Unfortunately skyrim itself is not multiplayer but there are mods out there attempting to make it that way
Getting your character lodged into places is an unfortunate occurrence in Bethesda games and the only way to become unstuck is to reload. Luckily, Skyrim offers about three autosaves, all very current, that you can use to load from.
Assasins creed all the way Skyrim is kinda hard and not as fun
Yes. If you kill your wife you can remarry. Be warned though sometimes it glitches and even while wearing the amulet of Mara you will be unable to remarry. I would suggest saving beforehand.

Yes, you can purchase and download it from Steam.
There are hundreds, if not thousands, of Skyrim mods. A mod is a game modification that alters the game in some way, be it mechanics, appearance or behavior. 2 places where you can find mods for Skyrim are Nexus Mods and the Steam Workshop (assuming you have the Steam version).

Not really. You can do small missions to take care of people, but there are no mercenary missions. Atleast none where you gain that title. the most way to be a mercenary is to go to any inn you can find and ask for work they should give you a quest to kill a random bandit leader or some random quest that you can do for gold this is about the closest to being a Merc you can get in Skyrim
There is currently no way to duplicate anything, except the Oghma Infinium and armor
No. When you have completed the quests, there is no way of getting it back!
