The fact is that very few lists available on the net care to report the names given to ac by the airlines. Most of these lists are usually dedicated to one airline. None that I know may answer your question.
The best, but tedious, way to get the names you want, is to review the pictures available on the net and read the names yourselves.
As far as N567FE is concerned, it seems to be named "Magnus".
For N375FE, it looks like a name around "Claude", but the resolution of the picture was not good enough.
