Profiled pipes drawing

I have now got 4 sets of 5 circles and I want create 5 pipes with each passing through the the circles I select. Can I do it this way because this is the easiest way to represent what I want.
I want the system to create nice curves in the pipes itself.
Or if not then how can I do this using the circle locations as a guide please?

Actually it is this drawing I meant to upload to illustrate the last question sorry.

Loft should do the trick. If you need better accuracy then what the basic loft does, you can add guidelines to define them accurately.

This video from the Shapr3D YouTube channel has some great loft and guideline help.
