My guess, with reasoning:
I'll second the glowplugs, battery, temp & Neutral selected.
As for the bottom four:
I guess the two almost identical ones bottom right are pressure & level, (one with the arrows being pressure) The "oil drop with arrows" second up on the left I guess is also pressure, but what?
Taking a slight tangent, the "oil drop with arrows" could be fuel pressure, meaning the "wavy" ones on the right could be oil - makes sense to know if it's both at pressure & enough of it? The fact the two wavys are clustered combined with Kubcat's guess at fuel filter drain would put the two fuel ones together bottom left, oil bottom right, pressure on the same row. It kind of makes sense to my brain.
Coolant (or lack thereof) would show up on the temp light.
