Chester Zoo ID Please For These Orangutans at chester Zoo

[sloggervlogger]

Could someone ID these Orangutans from Chester Zoo, please? I'm guessing it's dad Puluh. On the left the baby I'm not sure and I believe on the right is the sister maybe?
Thank you for your help in advance.

Looks a bit little to be Arga but I do think it probably is.

Puluh is always in the chutes where it is quiet and also cool during hot days. Definitely one of his favourite places to be.
