Controlling Parametric Nodes

I am having trouble trying to parameterize a few shapes I thought of. I am planning on making a bamboo vector screen that utilizes my nodes or shapes to control the density of the screen.

I plan on using a cnc machine to cut 2D geometries. Right now, the shapes aren't parametric and I need them to be. I would appreciate some help developing these shapes in grasshopper so that I can create variations in them. 

I included the rhino 5 file I've been working in that has the geometries along with the parameters I wish to control.
