So I came across some difficulties with the "Mix shader" node in cycles. I have 3 textures on a label: gold, paper and rough black letters.

enter image description here

How can I mix these effects? I can make 2 textures work together, but not the 3rd one. Here's the node graph.

Here's the reference. enter image description here

    $\begingroup$ Use the textures as masks to mix different shaders. All explained here: blender.stackexchange.com/questions/46424/… and blender.stackexchange.com/questions/109464/… $\endgroup$

The textures all have an Alpha channel perfectly prepared for a mask.
So you only need two mix nodes.

But I'd recommend making four different textures instead - Color, Roughness, Metalness and Bump. Then you just plug them all into one Principled BSDF shader, have more control and an easier life :).
