When I activated the theme in administration he made me install various plugins between these two.
What I don't understand is why inside the plugins folder (in the zip file you download on themeforest) there are various premium plugins that I can install as an option. How come there are also these 2 plugins if the defoult theme has already made me install them?

When you activate your theme several plugins are suggested to install.

When I download the complete package on themeforest inside the zip file there is a folder with plugins.
Comparing plugins in the folder there are other plugins (not recommended) but also duplicate plugins.

penci-framework
penci-framework (wpbakery right?)

They are both suggested and inside the folder.
Are they the same?
Thanks
