You have a slew of other addons installed and they are conflicting with nUI's management of the user interface. The reason your minimap is where it is is because of another addon that moved it. You'll have to either (a) remove the addon, or, (b) tell the addon not to move the minimap.
I *highly* recommend you do a proper clean installation of nUI as per this FAQ:

Start there so there are *no* conflicts, and then after you've seen what nUI does by itself *then* start looking at what other addons you want to add back.
