Answer 1

I guess your are trying to get all the records that matches fl_customer_profile and fl_users whether they are present in other tables or not, Inner join will return records if they are present in both tables , while left join will return all records from left table and from second table will return only matched rows

SELECT u.*,c.*,s.*,p.*
FROM fl_users u
INNER JOIN fl_customer_profile c
    on u.id = c.userID
LEFT JOIN fl_customer_subscription s
    on u.id = s.userid
LEFT JOIN fl_subscription p
    on s.planId = p.id
