You can't have one muscle that both elevates AND depresses a bone. So your question is a little confusing,
Upward rotation: Serratus anterior, Upper and lower fibers of trapezius
Retraction (adduction): Middle fibers of trapezius, rhomboid major and minor
Elevation: Upper fibers of trapezius, levator scapulae, rhomboid major and minor
Depression: Lower fibers of trapezius
Let me know if I left any out but this should be all of them!

.............................. the above answer is incomplete........
The trapezius is antagonist to itself, in that it can both elevate and depress the scapula
The Serratus Anterior moves the scapula forward and rotates it upward.
The Rhomboideus major and minor. With trapezius assisting.
inferior fibre of the serratus anterior muscles
Levator scapulae and Trapezius are the main actors, may be aided by the two rhomboideus.
That would be the upper trapezius, lower trapezius and serratus anterior
The trapezius muscle
rhomboids and middle trapezius
Levator scapulae
The Serratus Anterior moves the scapula forward and rotates it upward.
The serratus anterior is responsible for the protraction of the scapula. It pulls the scapula forward and around the rib cage, like when someone throws a punch. Often referred to as the "boxer's muscle". It is also responsible for stabilizing the scapula and assisting in its rotation upward.
Yes, both upward and lateral rotation are used to describe the same movement of the scapula. It's the movement of the scapula away from the midline.
The Trapezius muscles are involved in upward rotation of the scapula. However Trapezius is agonist/antagonist to itself as the upper portion elevates the scapula, the middle portion adducts the scapula and the lower portion depresses the scapula, while all parts are involved in upward rotation of the scapula. The Serratus Anterior assists in rotating the scapula (glenoid fossa) upward, (which would make it a synergist with the trapezius). The Serratus Anterior is antagonist to the upper and middle portions of Trapezius, so we are back to the agonist /antagonist relationship of the traps. That's about all I can contribute to this question.
the helicopter pushes forward when the pilot pushes the cyclic control forward. that rotates the blades forward . while pushing forward on the cyclic, the pilot must also pull up on the collective control. that will add pitch to the blades, thrusting the helicopter forward.

There are actually more than 4 muscles that should be immobilized. When you move your shoulders you move your clavicle. The muscles that causes movement at the shoulder joint should be immobilized. This includes the prime movers, as well as the assistant movers. The following muscles should be immobile. The subclavius which moves and depresses the clavicle as well as helps stabilize the pectoral girdle. The pectoralis minorabduct the scapula and rotates it downward, lowering your shoulders. The serratus anterior abducts the scapula and cause it to rotate upward, shrugging your shoulders. The trapezius stabilizes the scapula as well as move it, and helps extend head. The levator scapulae elevates the scapula and rotates it downward. The rhomboid majorelevates, adducts, rotates downward, and stabilizes the scapula. The Rhomboid minor does the same thing as the Rhomboid major. The pectoralis major adducts and medially rotates the arm at the shoulder joint; flexes arm at the clavicular head and extends the arm to the side of the trunk at the sternocostal head. The deltoid abducts the arm at the shoulder joint; flex and medially rotates the arm at shoulder joint; and extend and laterally rotates the arm at shoulder joint. The subscapularis medially rotates the arm at shoulder joint. The supraspinatus assists the deltoid muscle to abduct the arm at the should joint. The infraspinatuslaterally rotates and abducts the arm at the shoulder joint. The teres major extends the arm at the shoulder joint and assists in the adduction and medial rotation of the arm at the shoulder joint. The teres minor laterally rotates, extends, and adducts the arm at the shoulder joint. The coracobrachialis flexes and adducts the arm at the should joint.

Primarily the superior rectus muscle rotates the eye into upwards gaze.However, if the eye is turned towards the nose (facing intwards) then the inferior oblique muscle does much of the elevation.
