Eight tokens. Replacement effects are applied to each event they effect. If multiple replacement effects attempt to replace a single occurrence then the affected player chooses which replacement effect to apply and then applies any other replacement effects that are still relevant. In this case it means each parallel lives doubles the amount of tokens that would enter the battlefield.
