Just rebuild corresponding indices. Be ready that some of corrupted indices
will not be activated - if they are unique and data have duplicates. In later case
you need first remove duplicates and then rebuild index again.

Yes

ALTER INDEX <index_name> ACTIVE and COMMIT

Run gfix -v -f again after index rebuild
