Try this:
<dtml-call expr="REQUEST.set('rangList','folder1;folder2;folder2')">
<dtml-in expr="_.string.split(rangList,';')">
	<dtml-let folder="_[_['sequence-item']]"
                  index="_['sequence-index']">
		<dtml-call expr="folder.manage_changeProperties({'rang':index})">
	</dtml-let>
</dtml-in>

Also, why are you passing the folder ids in a string like this? Where
are these names coming from, a form?

If so, there are ways to eliminate the whole string.split. Also, the
code would not need to be this complex if the objects themselves can be
passed instead of a delimited string of ids.
