Do i need All in arma terrain pack to run the map Napf?

[Seal 4]

And if i don't, do i just need to use CUP Terrains core?

The development of AiA stopped about 1 1/2 years ago. You would need CUP Terrains Core because Napf is it's own independent map. You'd only need CUP Terrains Maps for maps that don't have their own mod, such as Chernarus.
