Probably not too old, but darn nice ones.
The fish is a carp. It symbolizes patience and endurance particular in the struggle to pass examinations and thereby achieve wealth through rank.
The flower will definitely have some symbolic meaning. My problem is that I don't know the name of the flower, but if you do, it's easy to learn its symbolism. The lotus stands for progeny or uprightness, the chrysanthemum stands for longevity or endurance. My guess is that the flower is one of these two.
The middle one has some calligraphy in the center. I can't see it adequately, but it probably is either the longevity character or the "good fortune character"
