From what I can see, I can guarantee that the Yensid Y, Alan-A-Dale chaser, Fantasyland shield, and Hop Low pins are fakes. They all are highly faked and appear in lots of fake pin lots from ebay and on cast lanyards. Other telltale signs:
Yensid - the colors are much darker and "greyer" than they should be. His eyes should be white and his mouth and fingers should be more defined. It also looks like the Mickey head at the bottom is lower than it should be. This alphabet set is very highly faked; if you find any pins from this set on cast lanyards nowadays it is 100% guaranteed that they are counterfeit.
shield - the purple should be brighter. The lines are also thicker than they should be, and there should not be that weird gap between the foot and leg.
Alan-A-Dale - very obvious border around the Mickey waffle print on the back, and one of the ears on the Mickey symbol on the front looks squished. This is an example of how even fake pins can have the nubs.
Hop Low - the yellow looks brighter than it should be.
I'm not nearly as familiar with the Aladdin/Jasmine pin or the series it comes from, but comparing your photo to pinpics I'd say you have a fake. The heart fill should be a bright lavender color and yours is more of a dusty rose. The lines also look slightly thicker than thy should be, and Jasmine's hair on your pin has a "puffy" look that should be more defined.
The sorcerer hat is trickier. The back looks ok. The lines on the front look thicker than lines on pins usually are, but that may be how that specific pin is designed. Without knowing the exact pinpics number of that one versus similar sorcerer hat pins, it's hard to say either way.
