They are all generic balls of light and there is literally no reason to shout the attack names out! Canonically though, the Ki-ko-ho is superior to the kamehameha!
I remember it was even stated that the Dodompa was more powerful than the Kamehameha wave. Then the Kikoho was basically in a class of its own. If we’re talking about sheer destructive capacity, I’d put the Kamehameha far above any of those attacks, but for its pound-for-pound sheer force- the Kikoho is definitely > the Kamehameha.
