No, any type of cousin can get married. But how the cousins choose to see each other is entirely their choice.
For Humeira-Ayaan, Humeira never saw Ayaan as a brother to begin with, but as a love interest. And Ayaan saw Humeira as a friend. For Haider and Zoya, they treated each other as brother-sister to begin with, especially Haider since he remembers Zoya, so since he's taken Zoya as his sister, that is the relationship they will choose to maintain.
Personally, I have a few male cousins I grew up with, whom I call and take as my brothers, and some others I'm not even in contact with, so I wouldn't see them as brothers. My sister too takes the same cousins that I do as brothers, and yet she'd married to another one of my cousins, whom obviously she did not see as a brother to begin with.
All about perspective here.
