grayish red
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.
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.
Shining a blue light through a cyan filter will result in a blue light shining through. As cyan is a combination of blue and green light, it will allow blue and green light to pass through it. Red light will be absorbed by the filter. This is proven by shining a violet or magenta light through the filter and it allowing blue light will shine through. It is shown as well by shining a yellow light through the filter which will result in green light shining through as both violet and yellow are a combination of red the other two primary colours, blue and green.
White light minus green light would appear as a purplish color. This is because when green light is removed from white light, the remaining color components combine to create a mix of blue and red light, which results in a purplish hue.

Green.
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.
