Based on the Activity Monitor display, you are not running Lion as your profile indicates, but Mavericks or newer. The newer OSX's will try to use as much RAM as is available, so what you are seeing is quite normal even though you are not using resource intensive applications. The new metric now is PRESSURE. If it is green, all is well. Orange and red become matters for concern.
