I always interpreted it as Diavolo existing "outside of time" when his ability activates. His own dimension of sorts outside of time and to an extent "casuality" or cause, leaving only "effect". But this is only when the ability is activated, and it has to be activated consciously. So it comes down to who activates their ability first as he wouldn't exist outside of time when it isnt active.

That being said, under those conditions, King Crimson beats out The World more often than not, and beats Star Platinum The World 100% of the time....due to Epitaph being able to see 10 seconds into the future. Due to that and Diavolo's cautions nature, he would activate his ability before Time Stop activates, and either he's completely unaffected due to being outside of time, or the 'time' that was stopped gets skipped over completely anyways. Or both. And even if it somehow doesn't, Diavolo is invincible while his ability is active.

Now, going by this he beats Jotaro 99% of the time. As for DIO, it depends on how long his time stop is at the beginning of the fight. If it's like how it was at the beginning of the fight with Jotaro, then Diavolo would have a chance to win provided he destroys DIO's head. Going for the head isnt his first option but if he sees DIO survive and regen, I dont think it'll be hard for him to try. Plus, DIO due to having weaker vampire powers than Dio Brando, wouldn't be able to regenerate his limbs as easily if they're cut off, which is something he does in character.

But if DIO starts with his Joestar blood at the greatest high, and has 9 seconds of timestop, either KC will erase all but 1 second of time stop and DIO would keep evolving passed the 10 second mark overcoming KC, or since Time Stop doesn't happen in "time" but "no time" it gets skipped when Diavolo skips and erases time anyways
