How to group Leads and Deals (from Zoho CRM) by week of the year in Summary Views?

How do I make the below two Summary Views?

  1. Grouped by week of the year. Leads and Deals. Columns = 
    1. # of Leads created
    2. # of Leads converted
    3. # of Deals won
    4. # of Leads lost

  2. The same as above BUT they are related e.g. # of Leads created, of those Leads how many were converted to Deals, of those Deals how many were won and how many were lost.
