Material Combine png images

It is a simple question but i cant find it anywhere so what i ask is combining multiple png images with their base color and opacity masks in material editor

use the lerp node. you would plug the two textures into the and b pin, and then plug the opacity mask in the alpha pin. Or lerp the top white pins of the textures together and lerp the opacity masks in a different lerp node if thatas what your asking

I tried lerp a lot can you send a image

it need to be look like this :
