Answer 1

Presuming that the relation is based on salesman and shop then try something like

SELECT 
    b.bill_no
    , b.saleman
    , b.shop
    , b.amount
    , l.credit
    , l.debit
FROM bill_status b
INNER JOIN ledger l
        ON l.saleman = b.saleman
       AND l.shop = b.shop

Answer 2

you can use Following.

Select * from table1 INNER JOIN table2 ON table1_billno=table2_billno;

You can use this query to get the data from both table where bill no of both table are same. You got my Point?

Answer 3

You are looking of UNION:

SELECT *, '' as credit, '' as debit
FROM bill_results

UNION ALL

SELECT *, '' as amount
FROM ledger

Make sure the tables has the same columns
