Yes, Bazz-B used his flames to protect himself, Äs and NaNaNa.

It's hard to say what happened to Shaz. On the one side, things suggest that he was killed, and although it's a waste to kill off a character just as its being introduced, Kenpachi killed 3 Sternritters off-screen. We only saw them the first time when they were already dead.

When Royd was mortally wounded and incapacitated while imitating Yhwach, the real Yhwach killed him. Of that, we could assume that he would have killed Shaz too if he was incapacitated. So whether he was incapacitated or actually killed by Ichigo, I think he's dead anyway.
