I would say #2 is an Amber then.

Butter would have red pupils and irises.
Gold dust would have dark Ruby pupils and yellow irises.
Amber would have black pupils with golden irises.
It's not a honey or lemon because the head stamp is wrong. I doubt it's an ultra carmel as not many people work with pure ultras. Chance it may be just a caramel because stripe sometimes also reduces the black, but I don't that too.
