Most likely words for ADEIMN are either MEDIAN or MAIDEN. EINN is pretty much going to be NINE (or NEIN [But I doubt that because DJMax]).
As for the 3rd Section, [D/O/U=A/C/D/F/O/R/R/U/ , C/I/E/R] I've no idea what the = Stands for. I'm thinking [3 Letters] = [8 letters] , [4 Letters]
For the 4th Section, [A/R C/O/R/S/S E/N/N/P/R/R/U/U/] (2 Letters, 5 Letters, 8 letters), I have a couple of ideas for the 1st Part. If this is indeed entirely English, they could be either:
OR, Leaving ARCRSSENNPRUU
RE, Leaving ACORSSNNPRRUU
NO, Leaving ARCRSSENPRRUU
ON, Leaving ARCRSSENPRRUU
SO, Leaving ARCRSENNPRRUU
Also, I agree with Seven Thousand.
