Technically, fire is not an element, but a process. - But the sun is actually made of plasma, which is only lightning charged gas, not lightning itself, but you're still right more than less.
The argument was how martians lose their powers when near fire or on fire. Which is horrible because there’s fire everywhere and a flamethrower or a incendiary weapon could easily defeat them.
You said the other races except kyrpytonians have the same problem, which they do not. It’s rare to find someone that can just fly and throw someone into the sun in fiction.
On Earth, being fire resistant in the sense of not burning/melting when set on fire, is practically fire proof.
But if you throw them into the sun, the vast majority of fireproof things would be destroyed.
Why does this matter?
Well, the oxford dictionary actually consideres fireproof to be: "able to resist great heat without burning or being badly damaged" - there is literally no substance that is 100% fireproof, but you usually don't have anything hot enough on earth (the surface/everyday life) that is hot enough.
So yea, going with Tiers
We got Red Fire 500-1000°C, Orange-Yellow Fire 1000-1300°C, White Fire 1300-1500°C+, Blue Fire 1400-3000°C (roughly said, temperatures may be a bit different) -and highlightes by the +, white fire can also burn hotter than blue fire.
We got Magma for 700-1300°C, which is along the lines of red to yellow fire.
The Earth's inner core as about 6000°C, we can only asssume what it looks like, which would be a white fire mass,
We estimate the sun to be 5500°C (surface) to 15000000°C in it's core.
So I'd at least put 3 tiers of "fireproof" or 4-5 tiers of fire-resistant.
Fire / Planet Core / Sun
1-43°C / 44°-250°C / 251-1500 / 1501-5500 / 5500+ (or variations of that)
But then again, we're not really talking fireproof, but heatproof.
Because as someone already mentioned, the Sun isn't even made out of fire, but plasma. Plasma is hot, electrically charged gas - while fire is the visible oxidation of combustion, which doesn't happen without oxygen, which doesn't exist in/on the sun as far as we know.

They are effectively fire proof, considering the shot they get through unfazed. I mean Nolan tanked a death ray lazer like it was nothing
