You can try using conditional aggregation

select display_name,
       sum(case when bill_month='Jan2k19' then package_price end) as first_bill,
       sum(case when bill_month='Feb2k19' then package_price end) as second_bill,
       sum(case when bill_month='Mar2k19' then package_price end) as third_bill
from
(
   SELECT u.display_name,b.package_price,b.bill_month
   from bf_users u inner join bf_monthly_bill b on u.id=b.company_id
)A group by display_name
