A bad pitch is called a ball by the umpire. If the bad pitch is thrown by the catcher and a baserunner advances it is marked in the scorebook as a "WP" (wild pitch)
It can either stand for Wild Pitch or Winning Pitcher.
you can walk or hit by the ball hit and run a wild pitch pitch runner
No ... no RBI is credited for either a passed ball or a wild pitch.
Any pitch from the pitcher that can not be caught by the catcher with reasonable effort.
Good question. The only thing that would be close to a WILD PITCH RBI would be if the batter swung at the pitch for a third strike, which of course the catcher couldn't catch. There would have to be a runner on third, and the batter would have to be safe at first on the dropped third strike rule. I do not believe that this would truly be an RBI though, because technically, a dropped third strike is like a walk, the batter is not credited with a hit.
Only if the bases are loaded and the wild pitch or passed ball is ball four.
No. You are credited with a stolen base and a run scored, but neither you nor the batter is credited with an RBI. It's the same way with scoring from third on a wild pitch, a balk, a passed ball, an error, or a double-play: no RBI is awarded.

Yes, if it just merely a dropped 3rd strike and he is safe, then he will be credited with a steal, however, if the pitch is ruled a passed ball or wild pitch, then the runner will not be credited with a stolen base, but rather just advancing on a passed ball/wild pitch
yes, the ball is not dead on a walk, the batter is free to try to advance to second and risk being put out
The batter would be charged with a strikeout and an at-bat, the pitcher would be credited with a strikeout, and a wild pitch or passed ball would also be credited. The batter's OBP would go down as the formula for determining OBP is (Hits plus Walks plus Hit by Pitcher) divided by (At Bats plus Walks plus Hit by Pitcher plus Sacrifice Flies)
Not unless the next batter gets a walk as well. Runners can only move on base hits or walks.
