6) The wall can not support the system as it is smooth nd can't counter the gravitational forces on The masses..the body simply can't be in equilibrium...
7) If the system is in equilibrium then the force on B due to A will be upward..it doesn't depend on the masses as the normal force is the one responsible for friction..nd that normal.force in This case isn't related to the gravitational force..
