Number 2?
It looks like a classic Moroccan Nimcha with 3 down-turned quillons and the fourth one forming a knuckleguard.
Some South Arabian swords had pommels resembling " Nimcha's" ( likely, an influence from Zanzibar), but I am unaware of this pattern penetrating deeper to the East.
There were large Arab colonies in S. India and Arab traders went as far as Indonesia ( Sindbad must have gone there on a weekly basis
)
We know about European and Indian influences on SEA swords. Are there any examples of Arab motives ? Inscriptions do not count: they are examples of religious Islamic influence rather than ethnographic Arabian influence.
I'll start: Indonesian Jambiya and Indian Haladie
