what is that called and how do I learn to read one? Any tips on reading it ? tutorial maybe?

That is a pretty typical way to represent a molecule.  We can plan reactions that attack various parts of the molecule, to predict outcomes, or we can count the atoms represented by the letters to write the formula, we can even use the info to try to predict how much energy we'd get out of it, or even what wavelengths it would absorb at.  Where did you get it, and are you interested in any of the above topics?

Those are skeletal structures of the caffeine molecule. Most organic textbooks should have examples dealing with skeletal structures. I am sure you can find tutorials on the internet also.

Textbooks dealing with chemical notation and nomenclature will explain you to read molecular representations as these and more complex.
