Nagato wins this one. He's not being controlled by kabuto this time so he'd use his skills effectively and efficiently. Using the kabuto controlled nagato isn't exactly appropriate as kabuto has no way of knowing how to use nagato's abilities as best as he can, especially when nagato had the skills all his life and kabuto just picked them up for 5 minutes.
Defence
Itachi is the biggest issue in this fight for nagato as his skills in analysis have shown to be quite troublesome. Along with the fact that he's able to shoot shuriken through blindspots, itachi is able to reproduce something of what he did to nagato. But, that's not to say it'd work again. This time, nagato isn't being controlled and doesn't have exclusive attention on 2 persons while itachi is no where to be seen. Nagato has no reason to let one of his opponents disappear from his sight. Therefore, Nagato simply uses his linked vision to keep an eye on each of his combatants - Considering he has manga intel on itachi, he'd know exactly what to avoid; Blindspot shurikens and totsuka.
Preta Path
This Path along completely screws over team 2. Because of preta, amaterasu and KCM cloak are completely nullified. I will repeat, using kabuto controlled nagato is a failed example as kabuto has no way of knowing how to effectively use nagato. Therefore, even though we didn't see him preta an amaterasu, it doesn't explicitly mean it's impossible considering amaterasu is

and we know that preta reduces all chakra based attacks to 0.
Thus, Amaterasu, Rasengan, Chakra arms, any raiton, any katon, any form of enton attack, and even susano'o(i'll get back to this) are all reduced to nothing. Thus, Team 2 are only left with shuriken attacks, genjutsu and taijutsu to defeat nagato.
Shinra Tensei
Everyone on team 2 is incredibly fast, but without a doubt, minato is the speed king. Minato is able to toss his shuriken at high speed to quickly use FTG to warp to nagato. This would be an effective way to damage nagato, but, shinra tensei would effortlessly blow away any attempts at getting close to him. Infact, Shinra tensei has an instant activation

and can blow away anyone in a split second, leaving his opponents with his 5 second interval to attack through. Because of this, any attempt for minato to tag nagato or even hit him would all prove fruitless. it would become virtually impossible for any of them to touch him without first having a distraction, but...
Asura PAth
The asura path allows nagato to easily cover himself during the 5 second intervals of ST. With asura, nagato can augment his body with additional limbs and rockets to counter attacks

. Infact, all shuriken jutsu are going to prove fruitless simply because of Asura path, and that'd leave ST available for split second Blitz attacks through FTG/Shadow clones/Shushin. Because of this, Team 2 only has genjutsu left at their displosal to use, but that is easily countered through Linked vision. As we've seen, even if someone's under genjutsu, they can still see the real world if they have

Therefore, Nagato is able to completely nullify team 2 and still have CT, BT, Summonings, Removing soul,
king of hell, and all 5 elemental ninjutsu at his disposal to use.
Nagato would win high diff simply because it's 3 elite ninja - Sharingan precognition and Ftg makes it harder to kill them.
