We say "De rien" (It’s nothing) in casual responses.

When someone says “merci” we says

We say “Pas de problème” (No problem) in casual responses.

We say “Il n’y a pas de quoi" (Don’t mention it) in casual responses.

We say “Je vous en prie" (You’re welcome) in formal responses

We say "Avec plaisir" (With pleasure) in formal responses
