These appear to be small hand-etched panes of glass.  It seems as if each participant wrote his/her name individually, perhaps as part of a College function or reunion.  Maybe even a Church of the Brethren group activity?  Names and inscribed information include the following, along with information included on some notes attached to the panes:

There are score marks in the glass that indicate these panes were never properly finished.  The pieces of glass look a little gooey and could use a cleaning, although the Archvist is at a loss as to how to clean these pieces without damaging them. The Archivist is not an Objects Conservator.

Perhaps these panes of glass were meant to be incorporated into a larger project.
