Herd masks

[Vipersfang]

This magical device costs one action to swap positions with someone wearing another herd mask. It says once per day activation.but are sold in multiple masks...

My question is .... is it one activation per mask so with two masks it can be done twice.⁰

I think so, yes.

The masks are separate items, there would be no reason for them to share a cooldown.
