Foundation has all of its styles wrapped in a mixin that prevents repeating it (ie. import once). This prevents you from reusing the code with different colors or other settings. Looking over the source of the mixin in question, you should be able to trick it into thinking the "module" hasn't been imported like this:
// the modules we want to import haven't been imported yet
$temp-modules: $modules;
.one {
// do some one specific stuff here
@import "styles";
}
// set $modules back to the state it was in before we did our import
$modules: $temp-modules;
.two {
// do some two specific stuff here
@import "styles";
}
// repeat as necessary
