Below is the query you need, you should consider keeping your naming conventions consistent because this helps visually and reduce bugs when writing code.

SELECT ed.emp_id, ed.emp_name , ed.emp_pf, emd.designation_name, te.pfacc1, te.pfacc2, temp. pf_percent, temp.pf_max
FROM dbo.emp_details AS ed
LEFT JOIN dbo.emp_designation AS emd ON emd.designation_id = ed.emp_designation 
LEFT JOIN dbo.tbl_empcontribution AS te ON te.eid = ed.emp_id
LEFT JOIN dbo.tbl_empdeduction AS temp ON temp.eid = ed.emp_id
