does "c" and "C" denotes the C notes from different octaves, "c" is one octave lower than "C"?

Also, as I understood, G>F means hold G for 1.5 beats and then F for half a beat. Why is not it written like this: G> F/, since / means hold note for half a beat?

How are delays indicated in this notation?

EDIT: what does (c4 c3) mean?
