Assuming 0 noise the other 3 simpler datasets are easy but the 4th spiral one seems very hard to fit perfectly within the limit of 6 layers even to use all 7 feature inputs.

you can cheat a little bit and use theta and r
theta is arctan(y,x)
r is sqrt(x^2+y^2)
but basically you can use x1 x2 sin(x1) and sin(x2) too, with a tuned model
