Multiple File Attachment Column in Document Library (SharePoint 2013)

Hi All,

As per default, i will have only one column to attach documents in Document Library . But i need to add multiple column for documents attachment in same row.

e.g. See below column

1)Project Name    2) Attachment 1      3) Attachment 2          4)Attachment 3       5)Attachment 4     

Kindly help me for creating such column (Hope there should be any coding requirements)
