Ice = Wind + Water, Wind is weak to Fire but fire is weak to Water. Ice takes on more of Water's attributes + there is a temperature thing with heating up the ice reducing it to Water which is Fire's weakness. Haku's ice dome tech was shown to be breakable by explosive things so maybe a Ice release user worse nightmare is an Explosion release user.

Wood = Water + Earth, neither element is weak to fire yet it burns and is in theory weak to fire.

Lava, Fire + Earth, anime briefly showed Kisame countering a Lava tech with a water release, fire is weak to it but earth trumps water. In theory, while you can cool down and stop the lava(providing its not a projectile) you still have to deal with the now cooled down earth and since a Lava user can use its base components as well, get ready for a earth spike counter attack.

Boil, Fire + Wind. Showed to be weak towards water techs in the anime. Fire hates water and Wind doesn't care.

Explosion either Earth + Lightning, or Lightning + Fire. Lightning does not hate itself unless wielded by an emo uchiha, Fire doesn't care while earth crumbles. As for why it would be deactivated by Lightning release, maybe the elemental is a delicate balance of explosive forces and adding in more lightning than need sort of "shorts out the fuse" or something like that. Like how you can disable something by giving it too much power.

All else were not shown elemental weakness of.

We are also forgetting that elemental fusions are their own separate elements. They are not one component or the other. They have their own identity, characteristics, weaknesses and strength. You just need the right genetics/biju/rikudo power up to access them. Stop thinking of them as collaborative and as individuals and it will become much easier to understand how "singular" elements like fire or lightning can counter them.

When we look at each other, we don't see ourselves as both our mother and father in one body having two different thoughts and all that jazz but as our own person with our own quirks and what not.
