Assuming that such an equation results in a precipitate can there be only be one precipitate produced, or sometimes do such equations result in more than one precipitate being produced?

Interesting question. Normally only 1 precipitated is always formed but there is not a rule that establishes that not more than one precipitated should be formed during a reaction. Imagine a solution of silver sulphate and you add calcium chloride. Silver chloride will precipitate while a small proportion of calcium sulfate (Gypsum), being fairly soluble, may precipitate as well.
Hey I remember doing this on the past: I added calcium hydroxide to a solution of copper sulfate . I used to obtain a mixture of copper hydroxide and Gypsum at pH higher than 4... So, that's it. You may get more than one precipitate in a single reaction.

There can be more than one answer here. While the previous equations are in fact true, the actual physical appearance and detection of more than one precipitate requires one to have the exact substances present and the exact concentration of each so that either the common ion effect or solubiizing effect on the Solubility Product Constant may be evaluated.

There can be more than 1 ppt
eg BaCl2 + Ag2SO4 ---> BaSO4 ppt + 2AgCl ppt
