Problems with my model in Model Builder

Hi !

I want to do a model with two iterators , one of rasters and other of shapefiles, but my model doesn't work.
I have a lot of rasters that I need to apply "Extract by mask" with different masks, I mean that in the tool "Extract by mask" I need each mask (I have 20 masks) cut my 33 rasters. For that I need a model with 2 iterators , one for the rasters and one for the masks.

Is it possible ?

And the last question , is it possible that in the name of my final raster will be the sum of the names of starter raster and the mask?

Thanks !!
