This means that those Surfaces are missing the textures that are assigned to them.

Select the element, go to its Settings Dialog and check which Surface is assigned to their various parts. Then, go to the Surfaces Dialog, select the Surface, and you will see in the Texture panel that the texture file assigned to the Surface is missing. Either delete the texture, or assign a new texture to the Surface. Alternately, you can write down the name of the texture file and find it in your computer (some kind of image file), and make sure it is in one of your linked libraries, or you can add them to your Embedded Library. That way, Archicad will find it and display it properly.
