All of these should be treated with a grain of salt. Many people today like to imagine that former kingdoms in their territories have distinctive flag and crest, but consistent heraldry is not a thing in pre modern Indonesia. I think at least a couple of these are modern invention based on hearsay, made very late in the kingdom's life under pressure by colonial gov who insisted European heraldry system to kingdoms which traditionally dont have one, or adhoc flags reported by Europeans who mistook it to be state-wide symbol adjacent to their heralrdy. A more salient symbols in traditional Indonesian kingship are usually heirlooms kept in the palace (crowns, keris, seals, sacred implements, etc) not heraldic badge consistently applied throughout their accoutrements. 

In short and imho, they should not be added at the moment.

Taking notes! :D

I just found the flags while looking for the rulers, so I tought I would at least suggest them.

You're the expert, after all, I just went of on a tangent :)
