Sorry if this is a dumb question, looking for a reality check.

I read on TRL's site that aluminum rings can not stand up to heat. I was thinking about making a candle holder and the rings would definitely be in close proximity (~2 inches?) of a flame, is stainless a MUST here? If I can use aluminum how about anodization, does that hold up to heat?

Aluminium melts at a relatively low point, I suspect this is what you read regarding
Anodization on aluminium isn't hard to damage, though I don't know that heat would with any certainty. I'll take a lighter to some later.
My gut would say try Stainless. Though heat will discolour stainless steel as well...

When in doubt, test.

The aluminum alloys TRL uses will begin to lose strength at approx. 350F or 175C. Direct exposure to a candle flame is at least 800C so it would anneal the metal making the rings very soft and weak. However, heat rises, so just being near the base of a candle or touching melted wax should not affect the strength.

The type of anodized coating used by TRL is only decorative, it will not protect the aluminum in any way. In addition, many of the dyes used will degrade at elevated temperatures.

Y'know, that might just be crazy enough to work!
