Can you just mention column names in text for used tables so that we can help.

Try to use distinct count
for the count columns
, and grouping by user_id
is enough as :
select o.user_id as "User Id",
count(distinct o.id_order) as "Count(Order)",
count(distinct i.id_item) as "Count(Item)",
max("date") as "Date"
from orders o
join item i on o.id_order = i.id_order
group by user_id;
User Id Count(Order) Count(Item) Date

You have to use INNER JOIN for user,order and item table. also use GROUP BY clause for group each date and order.
SELECT user_id,
count(o.id_order),
count(item.id_item)
FROM USER
INNER JOIN
`ORDER` o ON user.id=o.id_order
INNER JOIN item i ON o.id_order=o.id_order
GROUP BY o.Date, o.id_order
