I don't believe it is possible to identify the families, for these are just the Crests that would have appeared on top of a full Coat Of Arms and consequently would have been used by many families.
The only clues are the Coronets, the first, I suspect is supposed to represent a Viscount, although it should have nine balls, or perhaps it is a foreign order, and the second is that of a Duke.
Perhaps if you could find a Viscount that had a Griffin and Dragon as part of their Coat of Arms, then the answer may lie there.
