Margaret Mikulska has answered this question very well.  One note in
addition: according to Mozart's son, the name "Jupiter" for the Symphony
No. 41 was coined by J.  P.  Salomon, the famous impresario who brought
Haydn to London (and wanted to bring Mozart too).  As for the "Linz" and
"Paris," the names refer to the place of composition; the "Prague" was
written in Vienna but first performed in Prague.  Who first used those
names, though, I don't know.
