이 말들은 최근에 만들어진 신조어(new coinage)예요.
과즙 = fruit juice (과 = fruit, 즙 = juice) - it means "naturally juicy" (신선하고 생기가 넘친다는 뜻), not the extracted juice.
상 means a face or facial features, so 과즙상 would be a juicy looking (healthy, vibrant) face.
과즙녀 would be a girl or woman (녀) with such a face.
These seem to be very recently coined faddish terms (except 과즙, which is common), meaning even most native Koreans won't immediately understand what they mean. It also means that they might also be used somewhat differently.
