Photo 1 is an example of rembrandt. Photo 2 exemplifies split. Photo 3 is an example of either broad or short. Photo 4 is an example of loop. And photo 5 is another example for split. what I did for these photos was setting the light at the right angle so that they match up with the models, so that it gives the exact shot needed fo the above photos.
1, 3 and 4 are not Rembrandt or loop.
1 is close to butterfly light, 3 and 4 are split
