Offsets are always relative to the structure unless specified otherwise.
A "line" is 16 bytes long. You can read the line of an offset from how many 0x10 it has. 0x00 is line 0, 0x1C is line 1, 0x200 is line 32. To "skip a line" means to go to the next one, so if you're on 0x14 skipping the line brings you to 0x20.
"Magic bytes" is a general term for a specific value in a file used to mark it as a file of "that type". It's not necessarily a byte, it's often an int (4 bytes). Usually a file reader will make sure the magic byte is present and won't read the file if it isn't. Silent Hill games tend to use a date in hex as magic bytes.

Color shorthands are composed in pair of a color and how many bits this color has. for example, a red color of 8 bits will be r8, 32 bits rgba color will be rgba8888 and so on.
