Yes, it all depends on whether you have one or two tickets/PNRs. If it's different (budget) airlines, my guess would be two tickets/PNRs, but you need to check this carefully. Often budget airlines just sell point to point tickets for segments and don't offer connections.
BTW, you might want to use the red triangle to the bottom left of your post to ask a moderator to move this thread to the Budget Asian airlines thread, where people who have had experience with your particular budget carrier(s) might respond.
