So we know that Blue Rose Knights only works with ladies and not any men.
So why Captain Charlotte raised hand for Yuno during selection for magic knights?

I think you're misunderstanding something--men can join the Blue Rose Knights. It's just very uncommon.
From the Black Clover wiki:
The squad is mostly women, having the sharp motto of refusing the notion of worshiping or idealizing men. ... The few male squad members serve as errand boys. (emphasis mine)
I think that's where the mistake is. Men can indeed join the Blue Rose Knights, but the squad is primarily based and filled with women, and the men are just used as servants/errand boys. Explained above in the wiki, they do not like the idea of praising men. This does not mean they can't join the Blue Rose Knights. There's a few male members that just serve as errand boys for the women in the group.
So, Captain Charlotte raised her hand for Yuno because men can indeed join the Blue Rose Knights. It's just very uncommon, and that's why explained in the wiki quote that few men are in it, but they're just errand boys.
