typically no. H-W equilibiruim implies that no evolution occurs. Most populations do not meet the 5 requirments.  Most population have one of  the follwing:
    * mutation
    * gene flow
    * genetic drift
    * nonrandom mating
    * natural selection

No.

All of the conditions needed to maintain a HW equilibrium can be met (random breeding, large population, etc) except for one: no Natural Selection.  Natural Selection is ALWAYS at work.

Nope.  The Hardy-Weinberg equilibrium is a mathematical model.  Real populations are always subject to one or more of selection, nonrandom mating, genetic drift, occasional significant mutation, gene flow (via immigration) and the like.
