Let's not get ahead of ourselves (looks in mirror). So far the only confirmed saviors are Al and Emma. Some of the others mentioned could become saviors, but they have not been confirmed, any may not have become saviors.

I think one item that we got from "Street Rats" is that Savior Magic is a specific type of Magic, one that is very powerful. and given what Jasmine said to Aladdin, "YOU are the diamond in the rough", it may be that Al had the magic in him the whole time and just needed something to occur that woke the magic up. (It could have actually been the Indiana Jones Diamond on the Sword, but I interpreted the scene differently). Same with Emma, she had the Savior magic all along, and it just waited for the right stimulus to wake up (in her case coming to storybrooke and beleiving in magic).
