This is such a pretty mismatched set. All are hallmarked silver plate. 5 are similar in design, the classic French handle, the 6th is gloriously ornate, front and back. One of the set has a name engraved which looks like 'A Leruquer', but the script is difficult to read, the handle on this one is a little wavy. 
In France these would be used as pudding spoons, coffee spoons being smaller. 
I have not polished, although they would shine if required, but have left the patina intact. 
The teaspoons measure about 5.5" long.
