Solution

If a market is in equilibrium, is it necessarily true that all potential buyers and sellers are satisfied with the market price?

It is not true that all the firms will be satisfied with the current equilibrium price. The situation may be that a large dominant firm which controls a large share of the market supplies and the associated costs are lower than the firms with smaller share in the market and with higher costs.

The firms though are compelled to sell the product at the equilibrium price as they would lose whatever customers they have, if they sell at price above the equilibrium price. Consumers will shift to the alternated seller who are selling at the equilibrium price.
