What image asset do we need

[PH9]

For example: This less-than sign image is use for back button.
And designer want it to be size of 32x32 for the orange bounds that you can see.
What should we export? Just less-than sign image or less-than sign image with space?

My personal suggestion is to generate assets in the size they're needed at, e.g. the full 32x32 for the example chevron including the margins. Otherwise you'd need changes in layout code if the image is swapped out for something that doesn't share the exact same size and aspect ratio.
