Then where's the nobody's heartless and nobody? Nobody can apparently grow hearts due to DDD. So, where's Xemnas and the organisation heartless and nobodys? They had a heart and been defeated. Not only that, their nobodys can grow hearts too. So where's their nobody's nobody? And their other nobodys? Does the cycle of nobodys ever end? 

I think it's more like they're still nobodies, just nobodies with baby hearts. A nobody with a baby heart is still a nobody, and ofcourse only somebodies can have nobodies when they get consumed.

 

Aside from that, dying doesnt make a nobody, getting consumed by darkness or losing your heart does. Since we all saw that disappearing animation on almost all the nobodies, can't we assume they were still nobodies with baby hearts? Then they vanished and their baby hearts collapsed?

i dont think its a real heart. more like a makeshift replacement so i guess it doesn't come with all the side effects of losing it

Can, not necessarily did.

It's unclear exactly which Org. members were growing hearts or how 'far along' they were and I think that was done on purpose for this exact reason. If it was flat-out stated that Axel grew a heart entirely then this would be an actual issue, but we don't know how much of a heart he really had by the end of KHII.

One of the very fundamental flaws some fans choose to ignore. The very problem is that they are designed to be incomplete. Being able to function through body, soul, and memories (which I will debate about it if one tries to say memories = heart) and gaining new hearts. I can easily say this: i believe marluxia and larxene didnt want to gain their hearts back idk if it was in the novel. So we could see them with completely different personas.
