So, we know how The World works. Now, I'll try to explain how King Crimson works.

"Erasing Time" is more of a euphemism than anything. No time is truly erased. To people outside of King Crimson's ability, it would appear that time had skipped ten seconds or so. However, they haven't been "erased" completely, so to speak. For Diavolo (and those he introduces to his ability) the ten seconds pass normally. Diavolo is able to introduce or bring people into his time skip, that's how Bucciaratti was able to see himself. We'll get back to this. Anyway, anyone introduced to the erased time becomes exempt from fate. Apparently, everyone is fated to follow a certain path. However, when "time is erased," they need not follow this path. This is what Bucciarati saw when Diavolo erased time against him. He saw what would have been if he hadn't been introduced to the time erase, and he had the ability to act against that fate. A lot of Parts 5 and 6 revolve around fate, changing fate, etc. If someone is fated to die, they can avoid it by being in erased time. Doppio was going to be shot by Aerosmith, but because time was skipped, he was not affected by the bullets, which then hit Risotto. I speculate a similar thing happened to Narancia in the coliseum. First, time was erased. Then, Narancia was introduced to the erasure. Diavolo was then able to interact with him. He threw him against the iron bars, but because Narancia was exempt from fate, he basically started to float right through them. Then, Diavolo resumed normal time, Narancia was not considered exempt from fate anymore and was instantly skewered. Take solace in the fact that he probably felt no pain.

TL;DR: Diavolo (and others he chooses) can't be hurt when time is erased.
