They are all different ways of hooking the lure and presenting it. For instance, you can Texas Rig a Senko weightless - you insert the hook in the nose of the lure, turn it over and insert the point back into the body of the lure - then you can bury the hook, skin hook it or even leave it exposed. In addition to the articles you might want to do a youtube search for each of the rigs listed above - sometimes seeing makes understanding easier.
