Calling a person Haaji

Q: I was given to understand that Haji/Alhaj denotes a pilgrim in Arabic Language. After one has fulfilled his Haj and removed his Ihraam and returns to his native country he is no longer a Haji, i.e., a pilgrim. But, in my country India,  Hajis after their return from Haj Pilgrimage,
add a mandatory prefix title to their name i.e., Alhaj Umar for example, wherever they include their names whether it be wedding or other social invitations, letters, banners, media, etc. 

  1. Is the usage of this prefix title of Alhaj allowed in Shariah even after a Haji returns from Haj?
  2. Will it not be classified under Riy'aa ?(Showing Off)

Will a person come out of the fold of Islam by committing sin?

Q:

  1. I just want to be clear about this, if you do haraam things like receive interest from a bank, drink alcohol etc but consider them haraam, so if you consider haraam things to be haraam but still you do them, would you come out of the fold of Islam?
  2. A Hadith said with people little amount of Imaan will come out from hell but as far as I know Quran doesn't says people will come out from hell. Qur'an says those who enter hell will remain in it forever. So will those people be in hell forever and is above hadith correct?
