The Yasuhisas WERE successful (almost as much as Kaneki was although he was just a prototype), just not as strong as they were wanted to be.

As for Amon, his body could've rejected the kakuhou, causing him to become a floppy although he was otherwise a notable success.

As for Shirazu, ghouls can die if they can't heal fast enough to minimize the damage. He also had more Rc cells than the rest of the Quinx Squad. If that theory is true, it's possible that he had a higher chance to end up with TWO Rc types (the other being Rinkaku) than the rest of the Quinx but he was exhausted like heck as a result of spamming his kagune against Noro; Ukaku ghouls run low on stamina faster than other ghouls and they have a low Rc supply so that's part of the reason Shirazu failed to heal his injuries after breaking his frames.
