A green object absorbs all colors of light except for green. When white light, which contains all colors of the visible spectrum, hits the object, the green pigment in the object absorbs all colors except green, which is reflected off the object. This reflected green light is what we perceive with our eyes, giving the object its green color.
If an object is white in sunlight it will be green in green light. A white object reflects all wavelengths (colors) of light that shine on it. If only green light shines on it, that color will be reflected and the object will look green.
A "green" object is called "green" because that's the only color of light it reflects, and it absorbs any other color. If orange light is shining on it, then there's no light for it to reflect, and it looks black to you.
When you shine a green light on a green object, the object will reflect the green light and appear brighter or more vivid in color. Green objects absorb most of the other colors of light and reflect green light, so they will be most visibly affected by green light.
When a blue light shines on a green object, the green object will absorb some of the blue light and reflect the remaining green light. This is because the green object absorbs light of complementary colors, in this case blue, and reflects light of its own color, green.
The red object would appear black because it would not reflect any of the green light shining on it. Green light is the complementary color of red, meaning the object would absorb all the green light and not reflect any color back to our eyes.
Since an object is observed as the color(s) it reflects, a green object absorbs all colors and reflects green.

Green
It would be black becasue the object would absorb all the red light, and there would be no green light for it to reflect

A red object will appear dark or black in a green light because red objects absorb green light instead of reflecting it. This phenomenon occurs because the color of an object is determined by the wavelengths of light it reflects.
For exactly the reason that you call it a "a green object". You describe it that way because most of the time, when it's being illuminated by light of all colors, the only color that it does NOT absorb, and that remains to bounce off of the object and be seen by your eye, is the green. When there is no green light striking the object, it can't reflect any light to your eye, and it appears black.
A lemon would appear green under green light because the object reflects the color of light that it does not absorb. In this case, a lemon's yellow color would absorb all other colors except green, which it would reflect.
