There is currently one Kal-El.
So, there was New 52 Superman. Then Convergence Superman, who was supposed to be the classic Superman, joined the New 52 universe with his family. Then New 52 Superman died and Convergence Superman took his place as "our" Superman. But there was still New 52 Clark Kent, who was eventually revealed to be Mxyzptlk.
It was also revealed that - in some manner that makes no goddamn sense - Convergence Superman and New 52 Superman were two halves of the same whole. Old Superman and New 52 Superman were split into two by whatever nonsense DC is working up to with The Button.
So now, Morrison's t-shirt and jeans Superman is gone for good, with all the pre-New 52 stuff being replaced by the old continuity. The Wonder Woman relationship never happened. There's one Superman, he's been Superman for a long time, he's married to Lois, he has a son.
