ostaz Osama your question was:

        - What time you will finish your duty today?

I think 2nd & 4th of your answers are correct:

- Emta beykhlas dawamak al yom?

- ay sa'aa btkhlas shogol alyom?

but 1st & 3rd:

- Mata sayantahy dawamok al yaom?

- Ay waqt sayantahy amalok / shoghlok alyom?

       - what time your duty will finish today

   am i right
