If you need to group objects, you can select the objects in the object manager (using Shift, ctrl/cmd) then right click and select GROUP OBJECTS (about 2/3’s the way down in the menu)
Not to plug my own site (but I will) I have tutorials for beginners in C4D on my site, totally free:
c4dtraining.com
They are for versions 10.0 and up. If there is something specific in the tutorial for a given version, it is mentioned clearly.
