Odric, Lunarch Marshal

Multiple instances of any of the abilities Odric can grant your creatures are redundant.

Odric's ability triggers at the beginning of each combat, not just combat on your turn, whether or not any creatures you control have any of the listed abilities. If a creature gains one of the listed abilities before Odric's triggered ability resolves, perhaps due to another ability that triggered at the beginning of combat, then creatures you control will gain that ability.

The set of creatures affected by Odric's ability and how they are affected is determined as the ability resolves. Creatures you begin to control later in the turn won't gain any abilities or cause creatures to gain new abilities, and the abilities gained won't change even if every creature that normally had the abilities leaves the battlefield.

If one of those creatures has one or more variants of the listed keywords (for example, hexproof from white), creatures you control gain those specific variants.
