you need to input all good numbers for the door to open. You might want to download latest version, and check in the walkthrough around 25:30 if it does not work for you. I realize I gave you false information on inhuman, got tangled :(
croco and poly = 5+4+2
Inhu-el = 4+5+8
for NF you are on the good track, 6+6 and then not +0 but in a possible range if you know what I mean.
