Specific elements to scatter on surface

Hi everyone,

I’m new here and to Rhino with Grasshopper also. I’m trying to distribute 5 specific elements over dome surface. Just have no idea were and how to start. I was trying to use Paneling Tool plugin but its not what Im looking for, it scale and place elements on existing faces of dome surface.

So I decided to use and learn Grasshopper for this task.
Important things are, that elements should have fixed size, just should be bended depending on their location on the surface.

I would appreciate any advice or information about this. Thank you!

Here is attached image of the objects:
