You should tell us what manufacturer and model.
You should really try to find an operators manual. I am not familiar with that machine.
Seat belt and charging are obvious.
The ones that look like an upside down light bulbs are all engine lights. Glow plugs, air flow (I believe), attention (!) something wrong, coolant overheating, oil pressure.
The boxes with the drops are hydraulic oil. Hydraulic pressure, hydraulic temp.
I am not familiar with the green lights.
Most of these you can find by searching the internet for equipment warning symbols.
Hope this helps some.
