He has proven to have done so with his 5 elemental attack against the wooden Buddha. Not only that 4 of them elements are not his natural affinity yet they were equally as large and powerful as his katon.
Sure, but size and potency of techniques aren't the only factors to one's mastery over an element, but rather, how they're used and manipulated with examples being Sasuke's proficiency with Raiton and Kisame's proficiency with Suiton, but I'll admit, this is a good point.
Even if you I did agree with this, how does this imply that his Yin and Yang Release is actually on the level as other clan's member. Do you think Hiruzen has the potential to use Yin and Yang Release on par with an Uchiha and Senju respectively?
Also his chakra while preforming these attacks was 1/5th of it's normal and is had decreased since his younger days due to his old age. So the elements we saw edo hiruzen use aren't even the strongest nor largest he could do.
Clones only split the amount of chakra he possesses, but in no way have Kage Bushin been shown to have inferior usage of techniques.
Sasuke is a genius, He also copied lee fighting style in the same time span. Sasuke's affinity was and is katon as shown when he learn't it at an extremely young age to impress his father, Then again when kakashi thought it impossible for a genin to be able to use such elemental ninjutsu in the first place.
The mastery of his raiton was down to sasuke's ability to learn quickly and his overall genius status.
Elemental manipulation is a form of Chakra Control and it has been emphasized in Part 1 that Sasuke was not a genius in Chakra Control. That went to Sakura. Naruto and Kakashi both knew that Sasuke wasn't a genius in regards to Chakra Control and that even he had issues with Chakra Control as well. His ability to obtain both Katon and Raiton elemental manipulation within a similar time-frame suggests that he has an affinity for Raiton. Even if he were a genius, him having an affinity in Katon only implies he'd have an easier time mastering Katon rather than Raiton.
I also believe that Kakashi's statement with Sasuke's talent in elemental recomposition had to do with the fact that even with an affinity for Raiton, it still took a number of days in order to master it as we know that Sasuke isn't a genius in chakra control.
Well as i said, it depends on the individual and you might be right when talking about the average shinobi but we aren't here.
He was already shown high level of mastery of 5 elements, He has shown to be able to use Yang release via shadow clone jutsu and apprently has Yin release with his 5 in Genjutsu and the hype he was given in the viz here

Multiple ninja have a 5 in Genjutsu, including Orochimaru, but that doesn't imply he can use Yin Release or Yang Release on the level of those who inherited those techniques through their blood/chakra.
All that scan tells me is that he has a vast array of knowledge and experience in terms of jutsu. Him mastering over 1000 illusions does not imply that he can use Yin Release on par with clans who are respected for that quality as those illusions can very well be require a rather low application of Yin Release.
In terms of feats, there's nothing that even suggests that he has a high level of Yin Release when he was trapped and unable to break through a genjutsu that didn't seem very potent.
Well it's not like Ino nor shikamaru were profound geniuses in their clan, born with natural abilities above that of everyone else.
(Note, I'm not talking about Genius in terms of intelligence but skill and ability)
Yet constantly shikamaru was able to catch people in shadow possession way above his own level and Ino even managed to take control of war arc obito who was connected to the juubi even for an instant.
Of course not, but their proficiency of those abilities stems from their own clan, so naturally, they're going to superior in what they inherited compared someone like Hiruzen, esp. when he hasn't inherited Yin or Yang Release through his bloodline.
Then that just goes to show the type of genius kakashi is.
Yes normally a non-uchiha cannot master the sharingan but again you aren't taking individual skill/ability into the equation.
No, a non-Uchiha cannot master the Sharingan. Manga never made the distinction of what type of people can master a Dojutsu that's not there's. All that was mentioned is that the original owner has higher potential than someone who is simply "borrowing" their Dojutsu.
@bold, Yes but the rinnegan is slightly different from the sharingan. The Rinnegan takes incredible chakra reserves to the point not even a pure blooded uchiha like obito with Senju DNA couldn't use both eyes, He could barely handle one.
Databook confirms that this is not the case. The only difference is the level of strain it places on its user, but the Sharingan's effects on a non-Uchiha still applies:
Databook Translation said:
The trap created by great power
The "Mangekyou Sharingan" is a doujutsu that, with continuous usage, burdens the user with the loss of their eyesight. Since this is the source of "Kamui," using it in rapid succession puts Kakashi's body at risk as well.
[picture of Kakashi holding his hand over his eye]
↑Kakashi obtained his "Sharingan" though a transplant. The strain his body suffers may be far more severe than the a member of the "Uchiha clan" would suffer.
It's also important to note that in the context of the scan you presented, Obito commented on Kakashi's "mastery" over the Sharingan due to using it to complement his Raikiri, but this is something that Gaiden Kakashi and 2T Sasuke could so as well, so using just that scan doesn't at all prove that Kakashi had mastered the Sharingan.
Yet nagato, a person not born of ocular ninjutsu, whos body was not naturally accustomed to it was able to use both eyes since he was a child, before he even became a ninja or learn't ninja techniques for that matter.
Was he able to use it as well as Madara could once he obtained more experience?
No, he couldn't.
Another example of individual ability, Since on paper due to his lack of uchiha blood/Senju blood you would laugh if someone said an Uzumaki could withstand madara double rinnegan when an uchiha failed to do so.
That merely proves my point. If Obito was unable to use both Rinnegan whereas Nagato could, it only implies that Nagato's Lifeforce was stronger due to Yang Release being something Nagato inherited whereas it wasn't something Obito inherited.
