Yup they're both redeye flights with about 6 hours of flight time. With the meal service factored in and the usual takeoff/landing formalities, I'll say you'll be getting 4 hours of sleep at most.
On shorter redeye flights like this, meal options will be right after take off or 2 hours before landing I believe.
Not sure about KIX, but you could have your supper at the SKL in SIN and recline all the way (not 180 deg flat on the A333) once the seatbelt signs have been turned off.
Honestly speaking, it's very difficult to "maximise" a night flight in terms of service, if that's what you're looking for. Most people would choose to make full use of the business class seats to get some rest on board.
Bear in mind that SQ618 SIN-KIX is daily, however your return on SQ615 KIX-SIN operates on days 1,4,5 only.
