Yes. And kind of. From what is shown hand signs are used to manipulate chakra but tgere is a bit more nuance to nature transformation. Naruto required a lot if training to perfect it, but the war implies that a simple enough jutsu requires just knowing the hand seals and a basic understanding/skill of nature transformation.

Even jutsu of the same nature transformation requires a lot of practice though. Naruto got the Wind Rasengan fairly quickly but the Rasenshuriken wasnt complete/mastered for some time. Then fast forward to Sarada with 1 tomoe per eye copying a bunch of lightning techniques that were supposedly sword exclusive.

Given that the Sharingan can see/record/copy all the body movements and it can see chakra flow as well there isnt a reason it shouldnt be able to record and copy that as well. The only restriction should be chakra reserves.
