If you bought the game from steam, no. and if your trying to put a game on your computer and it keeps adding to steam, than un-install steam while your trying to install the game.
it depends if it is a game that is on steam (legit) it will go in there automatically if it is another game (for example, minecraft) then in the library, find add a game and pick "add a non steam game". if its not in the list then click browse and find it yourself.
You can't share a game between two accounts on steam, you'd have to buy the game again on the other account.
It is as are all the DLC for the game
Yes, some. Not all of them can be activated on Steam. See the related links for a list of the games that can be activated on Steam and for the instructions on how to activate a game on Steam.
You cannot turn a non-steam game into a steam game, however, you can add it to the list of your steam games by clicking the "add game" button in the "library" section. This will not make it a steam game, it will only cause the game to show up on the list.

Open steam, Browse the game you want to start and double click it..
No, because you are not using Steam to play the game, you are only using Steam to verify the game and to use the multiplayer parts of it. If you have a Mac version DVD/CD of the same game then you could still use it on steam if you register it on Steam.I THINK if you bought the Windows game on steam they will let you download the Mac version on the same machine. They have the full instructions on their web site.
Steam automatically pauses downloads when you run a Steam game so the only option is to play a non-Steam game (something outside of Steam).
no, it is a steam game

Dishonored is a Steam game, you need Steam to be running.
It is not Stream, my friend, its Steam, and its a direct - to - drive game mainframe, i.e. you buy a game and download it. but since you dont even know how to spell steam properly you propably didnt do it and you got a game that is FROM steam, steam version, and needs steam running to check for piracy. In laymen's terms, you didnt crack the game properly.
no it doesn't need steam
Steam version, meaning that any game that you buy runs of of steam engine.
Yes it will only if there is a code that comes with the game that you can enter into Valve's database.
