Sheikh, can we do ruquiya without wudu or in menstruation time ?and when we blow in water ? after reciting each surah 3 times or after reciting sura Fatiha, Last 2verse of Sura Bakara & last 3 sura?. should we recite loudly or i can read them silently?

No problem in reciting in the state of menstruation and you blow in the water after reading each Surah. You must move your lips at least when reciting it silently.
