From the chart given on Narutopedia most if not all of them make sense
Ice is chilled air with water
Scorch is Fire with fluidity of wind and absorbs moisture
Blaze is fire with the quickness of lightning
Magnetism is moving electrified particles with wind
They say the don't know wind and earth but it seems to me it would Sand release which is just earth molecules broken down by weathering
Explosion release is just exploding solid/earth like objects with heat and pressure (Lightning)
Storm release is moving lightning with the control and fluidity of water
Wood release is like living earth techniques whcih requires water and earth of course
Lava release is simple, just earth and fire
Boil release again self-evident water and fire
like NLee said nothing is set in stone on some of these but I think with a little bit of science and imagination, you can pretty much see that all the two chakra advanced types are taken as for the three such as Dust release, I really hope Naruto gets a three oneof his own cause I'd be so stoked lmao
