A.T. Robertson Commentary Matthew 25:15

"And unto one he gave five talents, to another two, to another one; to each according to his several ability; and he went on his journey." — Matthew 25:15 (ASV)

To one (ω μεν, ω δε, ω δε). Demonstrative ος, not the relative. Neat Greek idiom.

According to his several ability (κατα την ιδιαν δυναμιν). According to his own ability. Each had all that he was capable of handling. The use that one makes of his opportunities is the measure of his capacity for more. One talent represented a considerable amount of money at that time when a δεναριυς was a day's wage. See on 18:24 for the value of a talent.
