What is the maximum number of beneficiaries a life insurance policy can have?

Technically, the answer is 100.

When a life insurance policy is written, the option exists for the producer (or agent) to have multiple parties receive a percentage of the death benefit. Since percentages only run to 100 and inputs must be place in full integers, the maximum number of beneficiaries is 100, if they are all given 1% of the death benefit payout.
