For question 6: I know some of us put DACA and it was fine
Part 2: Application Type
It should be 1D - "I am applying for AP to allow me to return to the US after temporary foreign travel".
For part 3: Date of intended departure.
This is where it gets tricky for most of us because we don't now when USCIS will approve our case. I'd say just put the dates you are planning on going but try giving them a window, for example: if you're planning on leaving on October 10 then ask permission from October 5 to October 15. Just give give them and give yourself ample time to travel.
For question part 5: I don't think you're supposed to fill out this part. You can fill out part 7 which is if you're applying for Advance Parole which you are.
Hope this helps. Good luck!
