What are these female 2.54mm (0.1") crimp terminals?
You screwed up. There is no common name that I know of, at least not one used by a reputable manufacturer. The description you need is a crimp terminal that mates with 0.635mm/0.025" square post headers. The crimp terminal on the left clearly does not mate with a square post. 

One example is the from Molex which is the "SL Series".
