user233: In Buddhist iconography the figures are illustrated or depicted with various hand gestures.  The symbolic hand gestures are called mudras.  What is the significance of a Buddhist mudra? What are the various meanings for different popular mudras?

user233: According to Dr. Robert Thurman:

The mudra “is a sacred gesture symbolically expressing inner wisdom,
  or, in tantra, a female consort for yogic practices that harness
  sexual energies to the path.  Some of the main gestures we see in
  Tibetan images are abhaya, the gesture of fearlessness, the right
  hand held in from with open palm raised up: dana, the gesture of
  giving, the right hand held open and downward;
  dharmacakrapravartana, the teaching gesture, each hand held with thumb and index fingers touching and the other three fingers upraised,
  the two hands touching each other in front of the heart center;
  dhyāna, contemplation gesture, either one or both hands held flat in the lap; trisharana,  the Triple Refuge gesture, similar to the
  teaching gesture, with the emphasis on the three upraised fingers,
  representing the Buddha, Dharma, and Sangha; tarjanī, threatening
  gesture, with either hand held forward in a fist, the index and little
  fingers raised up; varada, boon-granting gesture, just like the
  giving gesture; and vitarka,  analytic or fine discernment gesture,
  like a one-handed teaching gesture, one hand held up with thumb and
  index finger forming a circle, the other three fingers raised up.” 1

Mandala: The Architecture of Enlightenment by Leidy and Thurman pg 168


user157: If I can give an answer with reference to 5 Buddha mandala as I think it draws together the iconography into a satisfying whole.
As it's name suggests the 5 Buddha mandala 5 Buddhas at each compass point with one at the center. Each Buddha displays their own mudra. Each mudra points to a quality of that Buddha and thus to a quality of the enlightenment experience.

1. Aksobhya The blue Buddha
Mudra is the bhūmisparśa or earth touching mudra. The hand touches the earth. This points to the imperturbable.

2. Ratnasambhava - the yellow Buhha
Mudra is the dana or giving mudra. The hand points downward and out (shown by NeilD). This points to generosity.
3. Amitabha - the red budda
Mudra is the meditation or dhyana mudra. Hands together (show by NeilD). This obviously points to contemplation
4. Amoghasiddhi - the green buddha
Mudra is the fearlessness or abhaya mudra. Hand is up and poitn forward (shown by NeilD). This is self explanatory I think.
5. Vairocana - the white buddha
Mudra is the wheel-turning or Dharmacakrapravartana mudra (again shown by NeilD). This which fits his central place in the mandala, bringing all the other qualities together.
