Bonjour!
Réponse :
1. If he were a rockstar, he'd have millions of fans.
2. If we were politicians, we would change the world.
3. If he were a dessert, he'd be apple crumble.
4. If you were a teacher, you wouldn't give any tests.
5. If she were president, she would help the poor.
Explications :
Pour savoir quelle fin de phrase utiliser, tu peux t'aider des sujets.

J'espère que ça t'aidera :)
