The trick is to identify fields common to two different tables, and try to find a path linking all the fields you want.

select
    mtpo.member_Id,
    mt.mshiptype_name,
    ts.timeslot_name,
    tt.timetable_name
from
    payment_option po
    left join membertopaymentoption mtpo on po.paymopt_Id = mtpo.paymopt_Id
    left join mshiptypes mt on mt.mshiptype_id = po.mshiptype_id
    left join timetables tt on tt.timetable_id= mt.timetable_id
    left join timeslottotimetables tstt on tstt.timetable_id = tt.timetable_id
    left join timeslots ts on ts.timeslot_id = tstt.timeslot_id
where
    member_Id = 1  -- change this

Also, I suggest tidying up the names of your fields and tables before it gets too late. They are quite messy!

I think this is what you want:

SELECT mshiptypes.mshiptype_name, timeslots.timeslot_name, timetables.timetable_Name
FROM membertopaymentoption
INNER JOIN paymentoption ON membertopaymentoption.member_Id=paymentoption.paymopt_Id
INNER JOIN mshiptypes ON paymentoption.mshiptype_id=mshiptypes.mshiptype_id
INNER JOIN timetables ON mshiptypes=timetable_id=timetables.timetable_id
INNER JOIN timesslottotimetables ON timetables.timetable_id=timeslottotimetables.timeslot_id
INNER JOIN timeslots ON timeslottotimetables.timeslot_id=timeslots.timeslot_id
WHERE membertopaymentoption.member_Id=$id

Note: replace $id in the WHERE clause with the actual memeber id
