When you say setup as goals, are you referring to separate conversion metrics? So, in the report view you have multiple metrics in the report metrics drop-down? If so, then yes, a single visitor could trigger multiple conversions for different conversion metrics. If I enter a test and reach action one (tied to conversion metric A) and then later reach action 2 (tied to conversion metric B) I would count as one visitor and one conversion for metric A and one conversion for metric B.
If you are talking about repeat actions for the same conversion metric that depends on the reporting settings. For Target based reporting the default setting is:
So they'll only count once per visit they enter the activity.
