These adjectives indicate a middle position on a scale of evaluation. Average and medium apply to what is midway between extremes and imply both sufficiency and lack of distinction: a novel of average merit; a digital recording of medium quality.
Mediocre and middling stress the undistinguished aspect of what is average: "The caliber of the students ... has gone from mediocre to above average" (Judy Pasternak). "Every writer creates weak, middling and strong work" (Frank Conroy).
What is fair or acceptable is satisfactory or moderately good but has room for improvement: a fair chance of winning; an acceptable grade on the test.
Indifferent means neither good nor bad and suggests a detached or resigned acceptance of such a status: "Burningham was an indifferent student at every school he attended ... and he preferred to be out of doors" (Andrea Cleghorn).
Something tolerable is good enough under the circumstances, but barely: "Tennyson ... suffered ... from illness fears, particularly of going blind, though he lived into his eighties with tolerable eyesight" (Carla Cantor).
