There is no Apple 5.25" drive that will work on a IIci. See http://www.vintagemacworld.com/drives.html.

You'll need to download the images in binary format and transfer them over a serial cable to the Apple IIe. You can use a modern Mac or PC with a serial port to do this. You probably need a Super Serial card in the IIe too.

The only way to write 5.25" disk images in a Mac requires an LC family model with the IIe Workstation card.
