What is figurative meaning?
We say a word, phrase, or sentence has figurative meaning when they go beyond their literal meaning. Figurative meaning usually comes from the use of figures of speech, such as metaphor, for example.
In the passage we are analyzing here, the figurative meaning is found in "they were my Supergirls." The author does not mean that those women were literally Supergirls - that would be impossible. But, by saying that, an inspiring voice is conveyed.
Therefore, the figurative meaning in the passage conveys the idea that the author admires and is inspired by the women mentioned.
