Hi, yet another question: is it possible to chain several pix_mask objects?

well, [pix_mask] will *set* the alpha-channel of an image. if you chain multiple [pix_mask] objects, you can reset the alpha channel of the image multiple times. this means that the alpha-masks won't accumulate in any way: if a pixel had alpha=1 after the first [pix_mask], it could have alpha=0.1 after the second and alpha=1 after the third [pix_mask].

this is most likely not what you want. instead, try accumulating the alpha-masks images before you send it to [pix_mask]'s right inlet.
