Menace is an evasion ability.

A creature with menace can’t be blocked except by two or more creatures. (See rule 509, “Declare Blockers Step.”)

Multiple instances of menace on the same creature are redundant.

Ward is a triggered ability. Ward [cost] means “Whenever this permanent becomes the target of a spell or ability an opponent controls, counter that spell or ability unless that player pays [cost].”

Some ward abilities include an X in their cost and state what X is equal to. This value is determined at the time the ability resolves, not locked in as the ability triggers.
