Hi Chregu,
IMO it is from left to right in your first pic up there: Kabeala from Sumbawa Island; Next one I'd like to see more pics of before giving my opinion; Sewar (Batak) from Sumatra; another Sewar from Sumatra; a Golok from Jawa.
If you can post some closeups of the Kabeala hilt, we might also be able to work out the type of ivory.
Cheers, Thor
