The ulna is not a midline structure. It is, however, the most medial bone of the forearm.
Correct. It is also proximally medial to the radius in pronation, however at its distal end it is lateral.
The right ulna is medial to the right radius. The right ulna is contralateral to the left radius.
The bone you are referring to is the ulna. It is one of the two bones in the forearm, located on the medial (little finger side) of the arm, next to the radius. The ulna plays a key role in stabilizing the arm and forming the elbow joint.
The trochlea is the medial process of the humerus. The humerus articulates with the ulna at the trochlea.

Antebrachium, medial to the radius
Inner? Do you mean medial? It is ulna.
In Western anatomical position, the distal ulna is located on the medial side of the forearm, next to the pinky finger and opposite to the thumb side. It forms part of the wrist joint, articulating with the carpals and contributing to wrist movements.
The trochlea is the spool-shaped process of the humerus that articulates with the ulna. The ulna's trochlear notch fits onto the trochlea for stability.
In anatomical position the palms are facing up, making the ulna the medial bone of the forearm. The ulna is on the pinky side, and radius is on the thumb side.
In anatomical position the palms are facing up, making the ulna the medial bone of the forearm. The ulna is on the pinky side, and radius is on the thumb side.
The radius forms the bump on the lateral side of the wrist. The ulna forms the bump on the medial side of the wrist. Remember to keep anatomical position in mind when determining directionals for the upper limb.
