Apple still has system 6 and 7 on their website if
you need it but getting system software from the net onto 400k floppies is
not easy if you don't have an old Mac already.
Apple has 6.0.8 and 7.5.3 and the 7.5.5 updater available as free
downloads. They do not have previous versions of System 6 or 7, nor later
versions of any OS revision.
That's actually OK, as performance wise, there is little difference on an
SE between System 7.5.5 and System 7.0 or 7.1. And .5.5 is more stable
and has better networking support, so there is really no reason to run a
previous version of System 7.
Same can be said for System 6.0.8 and previous versions. There is really
no reason NOT to run .8 so there should be no worries about lacking
earlier versions.
And although your comment about getting them onto floppies still holds
true, it is worth correcting that the SE uses 800K drives at the minimum.
Some of the SEs uses 1.44 drives. The best way to know is to look at the
front of the case. If it says either SuperDrive or FDHD, it is using 1.44
drives. If it just says SE, it is probably an 800k drive (also the back
label will likely tell you).
Hopefully this persons is a 1.44 drive, so they at least have a half a
shot at creating the disks on another computer. If they are in fact 800k
drives, that could prove a challenge almost as much as 400k. Later Macs
can't read/write 800k disks as well as the 400k, and PCs I don't think
can do 400 or 800 at all. (I think there are ways to get PCs to write the
1.44 disks however, and at least those are readily doable by any newer
Mac with a floppy drive).
