Challenge Complete! 
I created some objects in Blender to see if Unity can actualize the file and load the new added models, and Unity can do it, and other things that Unity can do is scale, rotate and move the objects acording to the coordinates in the native Blender file. The materials dont appears at beginning, so I had to remove the material and press right clic over the object imported, then select “Reimport” and that is how Unity shows the colors of the materials, just like Michael says in the video.
One funny thing is the position that Unity gives to the objects, as you can see in the next images.
