Arm is made up of three long bones: our humerus in our upper arm and our ulna and radius in our lower arm. our upper and lower arms are connected at elbow by a hinge joint between humerus and ulna. our radius and ulna are linked at our elbow in a way that allows us to rotate our hand and forearm by more than 180 degrees. our ulna bone forms the point of our elbow.

You would not be able to eat (jaw joints) or move (arm, leg, and neck joints).
The degree of freedom (DOF) of a robotic arm can be computed based on the number of the joints and types of the joints. For most robotic arm, the joint is either prismatic or revolute(about one axis), the DOF is simply the total number of the joints.
If the joint between your arm and shoulder was not a ball and socket joint, you could not be able to move your arm. Ball and socket joints allow you to move in most directions. Because of this, you can move your arm up, down, side to side, front and back, and around in a circle. The ball and socket joint is one of the four major kinds of movable joints. (The four major joints are ball and socket joints, gliding joints, hinge joints, and pivotal joints in case you didn't know.)
The joints connects the arm to the upper body.

yes
ball joints are parts of the front suspension. outside of the A-Arm
I believe on the 4 x 4 , with the torsion bar suspension , the upper ball joints are part of the control arm and the lower ball joints can be replaced separately or with a new control arm The 2 wheel drive , with the coil spring front suspension , the upper and lower ball joints can be replaced separately
that vehicle has a total of 11 grease fittings. two upper ball joints two lower ball joints, two outer and two inner ball joints, two on the idler arm and one on the pitman arm.
