None of the oneworld rtw products allows more than 4 flights in a continent outside North America (where the maximum is 6), so you won't be able to do all that Asia stuff simply within a RTW ticket. However, several of those Asian cities are connected by low cost carriers (I include MH in this definition these days on the grounds that it's cheap, even though it's still a full service carrier) which you could just do as side trips to the RTW ticket. SIN, KUL and BKK are all good hubs for the other Asian places (as is HKG).
