Customize Product List New Label

[Mimotxo]

Hey there,

I'm trying to find information but could not find how to create different labels depending on what type of product is,
I read something about creating different classes but I can not attribute to the products,

if you know of any examples, some information of how to get it ....

thank you very much in advance, I give you an example that I made with photoshop,

 

My second question is whether where the price appears, could put the name of the product as an adjunct in the second image
