Can you please post pictures of a few of them? Did all of them curl?

Repotting may have disturbed the roots a tad but they seem lightly wilted, like hydrangeas do in the summer when it is hot. If the soil is moist enough, they should fix themselves in the morning. If still wilted then, they had insufficient moisture in the soil so... maybe water them slightly more than usual... now that summer has almost started. While at it, check that the moisture is not evaporating on its own because it is hot in that room or because the sun is hitting them thru the window for a long time.
