Every high level ninja has some chance against every other high level ninja.
However there are many people that just don't have the skill sets necessary to fight evenly with Itachi. You need someone with a strong defense against genjutsu (it is obvious why), extreme speed (to dodge Amaterasu or to deal with Itachi's insane speed), high chakra levels(to try and outlast him), and intelligence(again, the reasons why are obvious).
Once you have someone with all of those attributes, that person has a better chance of beating Itachi.
I will go down your list and see who I agree with.
1) Minato - I believe that the only way Minato can win this, is if he has some sort of defense against Tsukuyomi. Minato always talks to his opponents just like Naruto and would be susceptible to this. Other than that I think he has a strong chance of beating Itachi.
2) Hashirama Senju - We don't know all that much about Hashi, but he has no real defense against Tsukuyomi (only two people really do), and he also is not very fast, and I personally don't see a defense for Amaterasu. His Mokuton would all burn. His only chance is to stay as far away as he can from Itachi and spam Mokuton.
3) Madara Current or EMS? Current Madara, yes, not easily but not with too much difficulty either. EMS Madara almost assuredly not. The difference between EMS Madara and Itachi is that Madara has more chakra, however Itachi's Susanoo has the Yata mirror and the Totsuka sword, not to mention Itachi is likely more skilled in genjutsu.
4) Hiruzen SarutobiTo be honest I just don't see anyway that Hiruzen can win this. By hype sure, but there are so few skilled genjutsu users that I don't think Hiruzen has come up against anyone of Itachi's caliber. Hiruzen also has no defense against Amaterasu, and no way to deal with Susanoo and the Totsuka sword. If Enma tries to block it he gets sealed. They both have fire, but Hiruzen has the elemental advantage of earth vs. water. Also I think speed would likely go to Itachi.
5) Sasuke (EMS-Susano-Amaterasu) Well Sasuke's EMS is entirely dependent on Itachi being blind, so yeah Sasuke wins against a blind Itachi. Otherwise no.
6) Tobi (Rinnegan - Six Paths) Tobi wins. Undisputed, the tailed beasts might get wiped out from the Totsuka sword but Itachi can't deal with Tobi + them.
7) Kisame Now here is an underdog that I actually think has a stronger chance than most would believe. The only reason is Samehada though. With it he is immune to most of Itachi's genjutsu (not Tsukuyomi), and can nullify most of Itachi's chakra based ninjutsu. However Samehada has shown that it can only absorb so much chakra at a time, and it doesn't really absorb fire well. (Itachi vs. Bee fight) So Itachi's win would have to come through Susanoo or Amaterasu. So I think Itachi still has the advantage, but Kisame has a chance.
8) Muu Dust release would be useless on Susanoo because of the Yata mirror, so Muu would have to become invisible to try and have a chance against Itachi. I'm not sure who would win from there, because it hasn't been shown that Muu has a defense against genjutsu, and seeing as he was killed by a genjutsu user it stands to reason that Itachi would win.
9) Naruto (KM and SM) SM Naruto loses due to limited clones and no defense against genjutsu. KM Naruto's only chance is to use KM clones so that genjutsu doesn't work on them. However this is only until the fox works with Naruto, in which case only Tsukuyomi would work, and Naruto knows about that already.
10) Third Raikage This one goes to Itachi every time. The raikages are known for brawn, not brains, and have no defense against any level of Itachi's genjutsu, especially Tsukuyomi. So that is an autowin for Itachi, but also he has Amaterasu and Susanoo. Amaterasu might not hurt the third raikage at first but it won't stop burning until he is ashes so it will outlast his shield. The Yata mirror is immune to any and all elements so his raiton armor attacks would be useless. However these points are all moot as he loses with genjutsu.
11) Tobirama SenjuI don't even want to write about this one as we know so little about Tobirama. From what we have seen in his fight against Hiruzen though it goes to Itachi, but we just don't know.
12) Yes, oh yes, the one and only, the infamous rival.. NAGATO
I could write a paper on this one, but I will keep it a few lines. If it is just Nagato I can see Itachi winning due to Susanoo and his genjutsu. No one is immune to genjutsu, they are always trapped in it, it just depends on their ability to break it. Very few people have the ability to break out of even Itachi's regular genjutsu. Coupled with the Totsuka sword that is all that Itachi needs.
However if Nagato has his paths, then Itachi has no feasible way of winning as his genjutsu wouldn't work since while he may trap a path in genjutsu, it is visual genjutsu and the shared field of vision would let Nagato know that one of his paths is under genjutsu.
Well now that I have written all of that I want to make it crystal clear that any of these people have chances against any of the others. I also want to point out that Itachi has started literally every battle off with genjutsu. I mention it in every response because he has used it literally every time with good results. Only Sasuke and Bee have gotten out, Sasuke because Itachi release the last genjutsu against him and Bee because of Samehada.
EDIT: For the Nagato response I meant to put genjutsu and the Totsuka sword is all the opening that Itachi needs. If he can prevent Nagato from attacking for even a few seconds he can seal him in the Totsuka sword. Actually he can do this to anyone, but some people who can break genjutsu fast enough, and are extremely fast themselves might be able to dodge. Just think about it though before you dismiss that idea. It makes sense.
Only because I'm bored lol Anyway, let me see......
1). Minato: We all know Minato is not an idiot, he was Hokage and it is still pretty debatable on who the more intelligent shinobi is between him and Itachi, they were both geniuses. With that said, Minato already knows a great deal about the Uchiha clan, and I don't think he would risk getting caught in any type of genjutsu, so he would be cautious about going into battle with him, maybe utilizing his FTG to hit blind spots, attacking from behind, the side, etc. avoiding direct eye contact, but that doesn't mean he still can't get caught because it's stated Itachi has more then one way to use it. Other then that, Minato also has a fairly strong defense, which is also less taxing. Anyway, my point is, I think Minato has a fair chance at winning against him.
2). Hashirama: I think Mokuton is a little underrated because we've seen it being used so much by Yamato, who said himself was nothing compared to the first. And we also forget that Mokuton has the ability to suppress chakra. With so much unknown about how he fights, it's hard to make an accurate decision, but by hype, I believe Hashi is more then enough to handle Itachi, he defeated Madara after all, which could also say something about his genjutsu defense. I don't think his feats during his Edo fight should really count as his full potential, so there really is no way of telling how fast he is. But like I said, by hype, he could win, but without much to go on, I can't really give an accurate answer.
3). Madara: I think Madara on both accounts can defeat Itachi, Current Madara for obvious reasons, plain EMS Madara definitely yes. Madara is one of the most powerful Uchiha in existence, in terms of raw and pure chakra, he can put much more effort into his jutsu then Itachi can:

I don't think Itachi is making fire on that scale. Itachi is smart, but I just don't think he has the stamina or strength to take him out. Even with the sword and mirror, Itachi from what we know only uses Sasunoo in desperate situations, unlike Sasuke, and by that time his stamina could be on E. I give these to both the Madaras.
4). Hiruzen: I agree with you here, I don't think Hiruzen has what it takes to take him out, although I don't think genjutsu would be the reason because he was a gifted genjutsu user himself, not even in his prime.
5). Sasuke EMS: Ummm, we just don't know anything about his EMS yet, but I'm just going to say no, plus like you said, Itachi would be blind lol it's kind of impossible.
6). Tobi + 6 Paths: I'm going to say yes as well. This is basically due to the ambush and overwhelming tactic that they seem to portray when they fight someone as shown in the fight currently happening. Itachi wouldn't know where to begin.
7). Kisame: I'm not too sold on Kisame having a greater chance then most because he himself said he was inferior to Itachi. He may be able to nullify genjutsu, but it would be just like a tailed beast to it's host, it may be too late if it was Tsukiyomi. Kisame would have to be able to close some space between him and Itachi to be able to still chakra, although him stilling chakra from Sasunoo makes me wonder if it is possible for him to do that?? I think that this fight will go to Itachi basically because they know so much about each other, and Itachi would be able to utilize the information a lot better then Kisame would.
8). Muu: Yes, Muu did lose against a genjutsu user, so it also makes me believe that genjutsu is sort of his weakness, but then again the Mizukage's genjutsu was definitely in a class of it's own, there was no visual caster so no one was able to detect if it was being used, while Itachi's is pretty much straight forward. Also, becoming invisible makes him completely disappear, no trace of chakra or body, this would prove difficult for Itachi if he ever let him do it, and it seems as if Muu is the type to go into a battle in stealth mode. With that said, Itachi would result to using Sasunoo due to Dust release. I definitely think he has a chance to win though, so I say yes.
9). Naruto SM KM: SM definitely not, I agree on this one. All the ninjutsu and Rasengan spamming will come to a halt when faced with Sasunoo, and he will eventually run out of clones and lose. KM Naruto I believe maybe he could. Naruto has been using clones on the level of Kages, so yes, using clones as distractions, Naruto may be able to get the upperhand, but another thing is that Naruto is not too bright. Naruto could win, but I give this to Itachi more then Nauto.
10). 3rd Raikage: I agree, he is not winning against Itachi, he has no defense against genjutsu, enough said.
11). Tobirama: Likewise, we don't know anything about him besides the fact that he uses water jutsu, and he has some kind of S/T jutsu. But I'm not going to go any further into this because we just don't know.
12). Nagato: I think a healthy Nagato is more then enough to take out Itachi, he has a defense to just about everything Itachi has besides the Sword of Totsuka. I posted a theory a while back about genjutsu and the Rinnegan, but it didn't get too much attention :/ anyway, what is says was the Rinnegan has more insight then the Sharingan thus being a better Doujutsu, and the Sharingan can see through genjutsu using insight, get it??? more insight, less chances of getting caught in genjutsu. Anyway, as we seen, Nagato starts off pretty strong, as we know his techs are more of the destructive variety, so Itachi would have to go into defense mode pretty fast, bringing out Sasunoo and his weapons. Not to sure on any feats from a healthy Nagato, but he would have to do a lot of dodging, but maybe a CT can aid in that. With the 6pop, Itachi again doesn't have a chance, they are just too overwhelming, and Itachi doesn't have the stamina to face them all.
So overall, the only people I don't think has a good chance at beating Itachi are Sasuke, Naruto SM, Third Raikage, Kisame and Hiruzen. People I'm not so sure on due to lack of info are Tobirama, and Hashirama. The rest I think have fair chances at winning, not saying it would be easy, but they have a chance.
So this ends my long ass response lol Don't know if I hit all the points, but just let me know and I can elaborate a bit more if you'd like.
