Antonio, since I'm one of the few up at this time of night right now (over here anyway) I'll start and then be corrected by the others.
Many of the weapons vary according to the different tribe, even the Moro tribes. One exception is the kris which was used among all the Moro tribes with variation in details (some lumad tribes like the T'boli and Bagobo were influence by the Moros and developed their own kris versions). Another exception is the barong that was used with variations among the Tausug of Jolo Island, the Samal, those Moros of Palawan, Tawi Tawi, and Basilan (not sure about the Yakan).
The Spanish did introduce some amount of influence in the north in some dagger and bolo styles especially in hilt styles, i.e. a knuckle guard. This does not include the Igorot head hunting tribes in the north.
With the Moro, the Spanish influence seems to have been more in the area of Moro armour with use of chain maille, plates, and especially the helmet.
Other "purly native" pieces appear to be the talibon (Cebu), the tenegre (Panay), the different head axes (Igorot tribes like the Kalinga, Bontoc, Ifugao, etc), the Bagobo bolo, the T'boli bolo, and bolos of the Tagakolo, among others.
Similar things can be said about shields.
Besides being part Filipino, the variation is another reason why I have collected PI/Moro arms and armour (not legs though
).
Hopes this helps as a synoptic start.
