Human anatomists restrict opposition to when the thumb is approximated to the fifth digit (little finger) and refer to other approximations between the thumb and other digits as apposition. To anatomists, this makes sense as two intrinsic hand muscles are named for this specific movement (the opponens pollicis and opponens digiti minimi respectively).
Moving a limb back to its neutral position is called reposition and a rotary movement is referred to as circumduction.
In the anatomical position of the hand the palm is facing forward. The thumb is placed in contact with the index finger. You can see the picture of the anatomical position. It is better to see than describe the same.
The fifth metacarpal articulates proximally with the little finger. The fifth proximal phalanx meets the fifth metacarpal at the knuckle of the pinkie finger.
In the anatomical position of the hand the palm faces to anterior side. Because you use your palm as you flex it. You do not use the dorsal aspect of the hand normally. So in the anatomical position the palm faces on the anterior side. That way the thumb comes on lateral side to the fingers.
No. When the body is in the anatomical position, the thumb is further away from the midline. You say that the thumb is lateral to the ring finger.

No, according to the anatomical position, the thumb is lateral to the fingers.

In the anatomical position, yes it is.
In the anatomical position, yes it is.
The thumb would be external in relation to the humerus, if the body is laid in the anatomical position.
The proper direction to count phalanges on the right hand in anatomical position is from proximal to distal. Start with the phalanx closest to the metacarpals (proximal phalanx), then the middle phalanx, and finally the distal phalanx at the tip of the finger.
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.
