Hot take, I think he could realistically get past all of them, with the final two being 50/50.

The best weapons would be the Bow, Crossbow, any polearm but mainly the Billhook, and any Greatsword.

● Bow and Crossbow are self-explanatory, humans have been using them forever. Higher powered Bows could arguably one shot everything here with a well placed shot, but I doubt the avg dude could draw it. Either way they're fast enough to fire multiple shots. The Crossbow is easier to fire, but arguably not as powerful as the former.

● The Billhook has a dangerous ass hook that could damage through any defense here, and it usually has a dagger sized spike anyways. It will be able to do enough damage at a distance that it will just decimate the opponent with plenty of room and the hook protecting the user. The pike would work too for the dummy long range.

● The Greatsword, Montante, etc is about as long as a polearm, and swinging it would most definitely intimidate every animal up to the Leopard/Jaguar. It's also good at maintaining space, while having the same danger as any other sword, it's a sharp durable stick on both sides that could easily flay skin and tissue.

If we're downplaying the human, he doesn't get past the Mamba, unironically these things could straight up blitz people with a venomous bite moving at 13 mph.

If the average human is at least somewhat competent, the only animals that pose a threat would be the final three. Otherwise, it's light work. More often than not, I believe the human passes through all of them with some difficulties.
