The best option would be the last one since it means something like i messed up. The question is a phrase that describes when you say something you shouldn't have said. the first one means he grabs her hair, that doesn't make sense so it won't work. The second one says she sticks her nose in everything. the third one is she is the girl of my eyes(or dreams because that's what it really means). The fourth one is Maintain your forehead high( which in Spanish it's like saying don't give up keep going, it's just in English it doesn't make much sense) the fifth is Give me your hand. The sixth one is it cost a lot, and the last one is I screwed up or I messed up.. so this one sounds the best
