I don't know whether there is a single git command to do it, but you can
copy those 5 objects "by hand": in your backup, you should have a
directory .git/objects, where you have the files
b7/1eb55f2dbc97dafd4a769fc61f346e69a5e0af
28/2035f3ae964e1e288f352c370be8edd11d3078

It should be sufficient to just copy those files into the corrupted
repo.
However if you packed the git-files in the backup (e.g. by running "git
gc"), those objects might be found in a pack in .git/objects/pack.
The easiest ist probably to use git-unpack-objects to unpack the
objects, and then copy the 5 missing objects.

PS: Well, I'm using git and I like it -- but I'm no specialist; so first
do a backup, before you follow my proposal ;-)
