1. ID looks correct except Calico perhaps, as I can't really see the lower body. If you can see Calico markings, I think that ID is correct.
2. ID looks correct. Chance of low expression Enchi perhaps. The lower body coloration is not Enchi-like, but the eye stripe is a bit more pronounced on this one.
3. ID looks correct.
If you want to post 4 to check for Enchi, could be confusing that for Fire, but you are probably correct if they look basically the same with heavy blushing throughout vs just at the bottom.
