If I had to say that anybody had a chance...
Naruto- Masters the Kyuubi and can use that chakra to outlast Pain. If he can put Sage Mode on top of it, then that'd be crazy. Plus, suppose Pain used Chibaku Tensei on a Naruto who had full control of the Kyuubi. The Kyuubi by itself isn't intelligent enough to get out of it, but Naruto may be able to. Plus, whatever this jutsu is that we haven't seen yet makes use of the Kyuubi.
Killer Bee- Eight tails mastery, and it'd be pretty damn hard for Pain to dodge the Menacing ball if he went full 8-tails because that thing was huge. Probably one of the most powerful attacks in the series and we are only assuming that it was full power. He has a very slight chance of pulling off a win, assuming that a full 8-tailed transformation is equivilent to Naruto's 8-tailed transformation
Madara?- We haven't seen what he can do yet. Though I wouldn't be surprised if he was strong enough in his prime to take out Pain. If he could, then I wouldn't be surprised if Hashirama could also do it, but he's dead so it doesn't matter.
Danzo- Supposing he had Shisui's eye ready to use, then he may be able to pull off a win.
Kabuto- Now he's more powerful than Nagato because he has control of him, plus Itachi, Kakuzu, Sasori, Deidara... If Kabuto were to face him and summon everyone but Nagato, then I'm sure even Nagato would lose because you have those four plus Kabuto w/Orochimaru absorbed.
Jiraiya-Though I don't see anything Jiraiya could do to counter Chibaku Tensei, Pain himself said that Jiraiya could have won had he had knowledge of his six separate bodies. I guess Pain knows better than anybody. Jiraiya's best bet would be to take out the Naraka Path, then hope to take out the Deva Path. After that, it's smooth sailing supposing he kept his arms intact fighting Deva Path...
I will put Sasuke before Itachi because Sasuke's new EMS power is bound to put him leaps and bounds above Itachi. Plus, Susanoo isn't going to work on a body who doesn't have a soul.
Also, look at this.

Susanoo had to grab the ground in order to keep steady, which means it is bound by muscle. Just like humans are.
So in other words, if Pain does THIS...

Pain will have more than enough time to have an opening to get to Sasuke or Itachi.
