Yang's emblance doesn't store kinetic energy, she absorbs damage. it's a limit break like in certain final fantasy games.

we know nothing about Ruby before he had her aura(and semblance) unlocked.

Blake's a bit more complicated than you seem to understand. it's been heavily implied that she was an assassin for the white fang, and her shadow semblance is closely related to that, while she has changed as a person since then her semblance serves as a permenant trace of her past actions. still, though, that doesn't tell us anything about how semblance relates to personaity.
