To answer your question directly without going much into why NOW would be a great time to put new rings on along with refinishing the cylinder walls- yes the rings DO rotate as the engine runs. Just space the gaps as far apart from each other as possible and you'll be fine.
Since you mentioned ring gap I assume you've had the rings off the pistons. In addition to what the other post said about putting the rings back in the right grooves- also be sure you have them right side up. Rings are usually made with a specific taper on the outer edge to help them seal and control oil...and although used rings might have most or all of that taper worn off- you'd still want them right side up. Most rings have a mark, usually just a dot, stamped in 'em to show which side is up. Be sure not to twist the rings putting them back on the pistons- they should spin freely in the ring groove without binding.
