Leaving out the mouse and joystick commands, the document you do not understand says that it is NEC-type signals. A NEC-type signal (for example NEC1) has three parameters, often called D (device), S (subdevice), and F (function). You can use IrScrutinizer to compute the Pronto Hex from these parameters (Pane Generate, select Protocol nec1, fill in D, S, and F, press Generate).
The statement
Custom Code + Custom Code : 8 patterns as below
33h+00h(Default; code1), 33h+11h(code2), 33h+22h(code3), 33h+33h(code4),
33h+44h(code5), 33h+55h(code6), 33h+66h(code7), 33h+77h(code8)
probably (I MEAN "probably") means that D = 0x33 = 51, S is 0x00 (for default), S = 0x11 = 17 (for code2), etc. The middle number in the table is the F. So to compute for example "ON", enter "0x33" (all the four characters) for D, 0x00 into the S field, and 0x11 for F. Press "Generate". Gives
