Better photos would greatly help on this but I will give it a try. Both top two look to be Luzon bolos WWII or later. Second down on right looks to be a late pira from Mindanao ?. Third down on right ???. Forth down on right seems like it could be a late minasbad, Bikol. Fifth down on right is a bolo from Negros, WWII or later.
Best,
Robert
