The only one that could make somewhat of a problem when forming them would be earth and lighting imo. Lighting due to it being unfocused as is, and in combination with this shape manipulation we would form a sort of a Chidori, although it being a failed variation of lighting rasengan which Kakashi tried to form. Earth due to its sturdy nature. Anyhow lovely job let's get going.
(Rasengan) - Spiral Sphere
Rank: A
Type: Attack
Range: Short
Chakra Cost: 30
Damage Points: 60
Description: Rasengan was a Ninjutsu technique developed over the span of three years by the Fourth Hokage, Namikaze Minato. The technique was taught to his sensei, Jiraiya, who then passed it on to Minato's young son, Naruto, years later. The technique is unlike many other jutsu in that it does not require any hand seals. It just relied on the ninja's ability to mold chakra. The ninja concentrates a contained, fast, rotating sphere of chakra in the palm of their hand, which can create a destructive impact.
(Yōso no Rasengan) Elemental Spiral Sphere
Rank: A

^ You've learnt these two.
For the next rasengan based technique you would have to have two clones on the field. You would form two rasengans; one in each of your hands with the help of clones, with each rasengan being capable of being used individually.
