what is the meaning and lucky number of Momina

For the meaning of Momina please see this page: Mumina

As for "lucky number", it is hard to believe that a Muslim is asking about something like this. Belief in things like this constitutes kufr (disbelief in Allah), so I advise you not to seek such things. All power belongs to Allah, there is no power in numbers, so there is no such thing as a lucky number, unless you think there is another god besides Allah who gives people luck based on some silly numbers.
