What are these components in green white and orange colour on this PCB?
The white components are ceramic power resistors. They are rated at 5W and have a resistance of 0.1 Ohms. They're sometimes used as current shunts in lower power applications.

The green components are most likely capacitors, usually in this package they're known as film capacitors. As pjc50 mentions, the values seem to be scratched off (odd thing to do to a capacitor). This suggests they might not be a capacitor, RC snubbers also come in this package type as well as other components. 

The orange components are without doubt capacitors.
