1. Since they are different keywords, yes you can use both. The same goes for Overthrow.

2. In that case, Zanya cast Clear Serenity, and Ninja Arts, Snake Gaze was cast by Ziun in response. Due to the "once per chain" rule, Zanya can't cast Star Crusher in response to Snake Gaze, since his Clear Serenity was already in that "chain", plus the fact that he didn't have enough gauge (which is why he cast Clear Serenity in the first place.

3. When something attacks, if you have, say, two CHAOS Tetra on the field, both abilities activate at the same time. When two abilities of a single player activate at the same time, they choose which one resolves first. The one that resolves last will be the one to be hit.
