You can use an aggregate function and a CASE statement for this:

select orderid,
  ordername,
  max(case when orderstatus = 'delivered' then orderstatus end) OrderStatusD,
  max(case when orderstatus = 'cancelled' then orderstatus end) OrderStatusC,
  max(case when orderstatus = 'delivered' then orderstatustime end) OrderStatusDTime,
  max(case when orderstatus = 'cancelled' then orderstatustime end) OrderStatusCTime
from yourtable
group by orderid, ordername

See SQL Fiddle with Demo

Based on your comments, you can use the following:

select * 
from 
(
  select c.*, 
    row_number() over(partition by orderid order by customerid) rn
  from customer c
) c
inner join
(
  select orderid,
    ordername,
    max(case when orderstatus = 'delivered' then orderstatus end) OrderStatusD,
    max(case when orderstatus = 'cancelled' then orderstatus end) OrderStatusC,
    max(case when orderstatus = 'delivered' then orderstatustime end) OrderStatusDTime,
    max(case when orderstatus = 'cancelled' then orderstatustime end) OrderStatusCTime
  from yourtable
  group by orderid, ordername
) table1
  on c.orderid = table1.orderid
  and c.rn = 1
