Hello! Could you tell me on which comics natasha is dating daredevil? And on which shes with tony stark?

The Matt/Natasha romance begins in Daredevil v1 #81 and ends when Natasha leaves Matt in Daredevil v1 #124.

Natasha was never really “with” Tony Stark.  They had a fake date in Tales of Suspense #52, Natasha’s first appearance. She and Tony hook many years later in Invincible Iron Man #317.
