I've used kayu sawo many times over many years, it makes nice hilts, supports carving well, nice tight grain, nice reddish sort of colour, finishes well.
All the other stuff you've mentioned I know nothing about, and I've never bothered with the botanical names of any woods I've ever used, or bought or sold.
But here is the Wiki entry on sawo:-
