How to make the appearance of path gradual?

Question

JavaScript

There is a svg https://jsfiddle.net/Virall/cecgvho4/4/ it has several paths, all these paths should appear in turn, as if a graph is being drawn, but now they appear simultaneously. Moreover, vertical lines should be drawn faster than two large curves, otherwise the effect of drawing the graph will not work.

Answer 1

I get it gradually, but not in order.
You need something like adding each next animate in complite to the previous one.
It turns out 1 animation is drawn, the next one starts.
