Rings of energy resist

[Question]

Do they stack with the benefit provided by spells like protection from energy, or resist energy?

No. They effectively provide the same benefit as a Resist Energy spell cast at a given level, which is why Resist Energy is required to create them. So they wouldn't stack with Resist Energy. Protection from Energy would overlap (but not stack) with such a ring, as it does with Resist Energy.
