would it be fiar to say that riku is mickey apperentice( he has guided him through the whole time that they've known each other) and sora has been being taught by ventus technically with his abilty he has now can't just be from swingin

Ventus never became a master. But it wouldn't be a stretch to say Mickey could be Rikus master. However they seem to have more of a partnership, Mickey seems to view Riku as something of an equal, and follows him on the path of Twilight.

No, not really. The word apprentice is more...lowly in a matter of speaking, and while Mickey did guide Riku and support him on his journey, it was because they're friends. Ven hasn't taught Sora anything; note that Sora has been sparring with Riku since he was a small child. That's where the experience comes from: constantly sparring with the other kids on the islands to build combat experience.
