kakashi cant because he cant make clonescan u put lightning chakara on rasengan just like rasenshuriken?
Not too sure about that, a Rasengan with enough chakra put into it can be just as devastating. It all depends on your opponents element, if you're at a disadvantage with lightning using a Rasengan with no element attached to it would be more useful.Raikiri is better.
No, he can, in the end of his fight with Zabuza, he made many clones.kakashi cant because he cant make clones
