Crested Gecko morphs are more variable to interpretation than with other species such as Ball Pythons or African Fat Tails. This site will help you out a lot to start to understand what to look for in morphs.

I've tried refreshing the page a few times and for some reason it just keeps loading with some incomplete pictures. From the looks of it almost all of them are tigers or brindles (the pictures that load) with a couple flames. Take a look at that thread I posted and try to analyze what you have. If I can get the page to load in it's entirety I'll post my opinion of what all of them are.
