Not exactly.
From my observation, Dragon Slayers- at least of 1st and 3rd gen- when developed enough, gain the ability to eat the element of another slayer and impress it on themselves, gaining a double mode.
Gajeel was pretty explicitly trying to copy what Natsu did with Laxus back in the tournament, under the logic of 'if Natsu can, I can.'
Future-Rogue did this with Sting's light as well, remember. Though the fact that even he, despite being stronger than Natsu and older, only has two suggests two's the limit.
What this suggests is that Natsu/Gajeel *could've* gotten any of those elements (they could both be iron/flame dragonslayers, just with different primaries, even!), but once they have two they're probably stuck with those two.
