usually people cross their fingers when they wish for something to happen for example, you could say " cross your fingers for mom to say yes to the sleepover!"
Explanation: Cross your fingers is usually used to wish luck and if you want something to happen you cross your fingers.

If you try replacing it with the other words, it wouldn't make sense.
