You cant gain more claw attacks than you have limbs to use them. in this case, give the player the best dice out of both claws, but they dont get extra claw attacks.
The player is doing this because the later powers of the beast totem are extremely powerful, and the lesser one is often considered a tax, even if you dont get any use out of it.
The rules on natural attacks not granted by the natural form are very light - the CRB was written with only PCs of the core races in mind. There are no actual rules that say you can't have two claw attacks on one hand, it's just implied that your normal fingernails grow. I think almost every GM uses a "one attack per specific body part" rule, with varying degrees of what counts as a body part for that. Llowest common denominator would probably be something like "one bite per mouth, one gore per set of horns/tusks, one claw per hand, one slam per appendage".
Having natural attacks on all limbs is again not explicitly prohibited, but unintended. Felines have only two claws, equines have only two hoofes, etc. For animals that have claws on all limbs, the Rake ability shows under what ciorcumstances they can be used, i.e. when the animal literally jumps onto the target. Otherwise, one set of legs is reserved for standing on (because otherwise it'd look like this).
Still, there are creatures that ignore such limitations, most famoulsy the cute little Deinonychus dinosaur - the talons are the hind leg 'claws' (maybe it flutters when making those attacks?). It's also not hard for a perfectly legal PC to have more natural attacks, a Weretouched Shifter tunring into a deinonychus being a perfect example (bite, two talons, and can use the Shifter's Claws class feature for two claws, all that and pounce at 4th level).
In the end, that the player will have fun with their character is important, but so are the other players - having one PC overshadow other's is very bad. Without knowing the other PCs, what books are allowed, and how far the player is going to optimize the character, it's not really possible to make a good call.
Making one set of 'claws' secondary would greatly decrease the impact, the damage increase is about half as big. Be wary that Greater beast Totem inreases damage and crit multiplier for claws, you might not want to apply that to both sets.
giving the player 2 extra attacks will Be very powerful.
what I would do is when he rages. the size of dice for the claws with the biggest damage dice increases one step.
its for toothy.There is a FAQ that says you can’t have two bite attacks unless you have two mouthsLink/source? I can't find it.
And the award for most useless FAQ goes to... Seriously, it talks about "in this case", and then later makes the statement "Generally speaking, natural weapons can only be used once per round each." which is not only just plain wrong (you can do that with e.g. Haste or the Multiattack ability animal companions have), but since the question was about having two different "bite" natural weapons, it#s totally missing the question!

You'll get over it. : D
Don't worry, I'm fine - the real award for most useless FAQ has been given out a long time ago, anyway: this FAQ literally tells us they "haven’t reached a final decision on what to do". The FAQ does absolutely nothing, never did, and never will. To add insult to injury, they also get their own rules wrong - they presume a rule that says that "bonuses don’t stack from the same source", but the actual rule in the CRB explicitly only applies to untyped bonuses.
I know the player hasn't ever played pathfinder before, and don't know as much about it as I do. They've just always wanted to play a character that focuses on natural attacks.
As a follow-on to the original question. (And I know this is venturing into Homebrew) How overpowered would it be to allow the character to have access to an additional two claw attacks, since in my mind feet are limbs.
What if I make one of the two pairs secondary attacks?
There's actually an FAQ that specifies that claws go on hands and talons go on feet (for humanoids)
At low levels giving them double the natural attacks will be very strong. It gets weaker as you level up though.
