How to draw reusing a mesh?

I'm not sure what's the best way to draw a few instances of circles.
And don't really understand how it's drawing them.
Currently i have 1 circleMesh i get from ofPath.arc and then getTessellation. I'm not sure how to duplicate them

I have a vertex n frag shader that i use to animate the circle's texture and set it position by supplying in my mouse position. I use the position to make sure my animation is always displaying in the center of the circle as well.

As a test i'm trying to add a 2nd circle, in future i might have N number of circles, each can be sharing same shaders, or some might have their own frag shader animation.

How can i add a 2nd circle? Can i reuse the circleMesh, and just tweak the "position" i supply the shader for each circle? Do i need to duplicate each shader or i still use the same one?
