Banu 1 bleeds and discards a card using Haqims law retribution.

Can Banu 2 take over the bleed with Mask of a 1000 faces, and use the same HL:retribution to discard a card for + 1 bleed?

No, the BH:R has already been used once "during the bleed action" ("during X do Y")

Name: Haqim's Law: Retribution
Cardtype: Master
Clan: Banu Haqim
Put this card in play. During a bleed action, a Banu Haqim you control can discard a combat card to get +1 bleed.
