Conditional generation provides a special field so you can check which card you are rendering. If you wanted to display the “hint1” field on the first cloze, and “hint2” field on the second cloze for example, you could use the following template:
{{cloze:Text}}
{{#c1}}
{{Hint1}}
{{/c1}}
{{#c2}}
{{Hint2}}
{{/c2}}
