I agree that that newer kris is more recent and perhaps Sulu. The Maguindanao kris seems to be the oldest of the lot.
The "Maranao" kris might also be actually Maguindanao as well (based on the front of the ganga, hilt form, and scabbard). The white metal does look like silver, but close ups would help and you might want to get it tested to see if it's nickel-copper alloy or silver.
I would also agree with your caution on online auctions. Harder to discern quality or details if not in hand. Glad you were able to get these for good pricing as well as being able to inspect these up close. Congratulations!
