I'll make this short and simple and dumb it down for the clueless users who can only defend main stream characters (most of the current site ofc).
Konan:
Konan uses Chakra to make her body Paper style. No mater the material

and

if you hit her ofc. SO as long As Hiashi has Gentle fist,

is all he needs to defend then cancel any chakra based attack/weapon/substance

. And before she would form or reform, no matter where she is at The Byakugan will at all times know her location and where to attack. And with he use of chakra detonating the Explosing tags he will know when to defend or retreat.
Beats Konan.
Hidan:
All though Hidan is immune to "death", that doesn't mean he does not

. He still has chakra and still has to move and function just like every other human. With Juuken; One could not only close his chakra network with 64 palms and prevent him from moving, Juuken also allows him to dislocate some of the internal things in his body like

plus the fact He could simply

when he gets a good look.
Beats Hidan
Kakuzu:
Kakuzu loses just as easy as Hidan TBH. His fighting style relies too much on secrets and chakra. Byakugan see's all his secrets before he even knows Hiashi knows. Byakugan see's the flow of chakra in each heart. And with the Byakugan will know every single move Kakuzu attemtps before he even produce an attack. Thanks to the insight of the chakra network, any thing chakra based is seen before it is release since chakra has to first be mustered up.
-Diamond skin is uses if he isn't fast enough to react and use the jutsu in time. But ofc it already doesn't matter since Juuken attacks the insides and one hit can destroy any of his hearts to the touch.
- Elemental attacks are useless since Juuken>Chakra based Substance. Vacuum palm plows through any attempt and easily one shots any heart monster and/or Kakuzu.
-Taijutsu obv equals death for Kakuzu.
Kakuzu loses.
Itachi:
Itachi is outclassed in Taijutsu but doesn't know it. But ofc once he figures it out would retreat. His Ninjutsu is usesless because of Juuken, any and every Fire jutsu is plowed through with Vacuum palm. And ofc Genjutsu is restricted so no need to mention how he easily counters that.
-Amateratsu; Is the reason Itachi would lose tbh. Ama' requires a charge time.... lol... Byakugan see's anything Chakra related and see's the area you are using chakra at. Ama is countered before it is even released. With Juuken layer, then Full body burst it is easily Dispelled and removed. And with teh major Drawback MS causes he will be left wide open for a counter attack.
-Susanoo; The only real threat tbh. But what would SUsanoo be able to do? Protect him forever? Non-legged susanoo makes the user slower and stationanry for the most part. Itachi's susanoo attacks are way to slow to hit him, plus with teh byakugan Hiashi would know Itachi's chakra levels at all times. Plus know that something is wrong with Itachi's health. Only a matter of time till Susanoo runs out and itachi collapses.
Itachi beats himself.
Deidara:
Tricky one since he is an aerial opponent. Hiashi would see his style of fighting and know the clay is his secret to victory. As seen with neji he will know when any of teh clay will explode before it explodes. And if he uses Juuken Vacuum palm to hit them before they explode then he makes them Duds. If Deidara realize to just use C3 and get it over with in the air then he wins with Village buster. But If hiashi beats him before he learns even C4 is usesless (wince Hiashi would know they are micro bombs and to not touch or breathe them in, plus see Deidara is just outside the distance like sasuke did).
C0 tie.
Sasori:
Anyother tricky one because of Hiruko. If 3rd Kazekage isn't used off bat or asap he loses no diff. But because of The 3rd he could gain distance and attack non stop with Iron sand, then eventually cover most if not all teh battle field and attack from below and keep him from spinning then its a wrap.
loses if 3rd isn't out off bat. Could win if he gets the 3rd out fast enough before dying.
Tobi:
Obito? Tobi? Young Obito? too many to choose from, don't even wanna touch that subject.
Kisame:
If he absorbs before Hiashi gets close and stop his heart (since you cannot heal something that is not in need of repair), Hiashi could like Evani stated attack his organs. But that's if his chakra makes it far enough to penetrate. Fusion rapes hiashi like no other though.
Kisame wins.
Simple brief summary. I don't expect most to get since I didn't post pictures to show.
