1. Ananias is kicked out, and the battle is Lot's Wife and Sapphira. Sapphira cannot indirectly negate herself, so the FBTN stays regardless of anything else (even if Lot's Wife had banded to her directly). She can negate Lot's Wife, which is why Ananias is kicked out. However, Ananias cannot be negated, so the band to Sapphira sticks.
2. All of the bands that are not CBI or CBN are negated, and those characters are removed from battle. All effects that are not CBI or CBN on the banded characters that are removed from battle are cascade-negated (so if Scribe underdecked an enhancement, that is negated). Only Lot's Wife remains with the cards you indicated.
