How do I extract items of a list one by one and not as a group?

Your problem is related to data structure...when you pass both components into your mesh input, the mesh input identifies them as belonging to different groups because they have different data tree paths assigned to them. The easiest way to deal with this is to right-click on the input to your mesh and select "flatten", which makes assigns all of your input data to a single path.

Oh!!! Thanks a lot. I was always wondering what these options do.

Do you have any reference or link where I could study more about them?

Data structure can be pretty tricky.  David Rutten just did a webinar you should be able to find about how to use them. Otherwise, I'd use the search bar on the website here for data structure tutorials...

"Data structure can be pretty tricky."

Actually that's the thing which takes 70-90 % of the time to do anything with grasshopper. I would say complex rather than tricky.
