Answer 1

To align easily things in bootstrap 3, You should use the Grid System.
Here is a fiddle close to your needs :

    

       

        Quarter
        

        
   
    

        

        Address
        

        
        

        Addr. №
        

        
    
    

         

        Block name/Number
        

        
        

        Entrance
        

         
         

        Floor
        

         
         

        Apartament
        

        
    

The alignment depends on the width of the screen so be sure to tune it properly to your needs. Then you can style the inputs themselves.
