A funny one! Don't worry, I'm here to help. "Pusa" means "dog" in Filipino, but in this context, it's being used as a colloquial and affectionate term to refer to a child. The phrase "kakapanganak lang" means "will be born" or "will give birth", and "limagiting" is a word that means "five fingers". So, if you translate the sentence literally, it would mean "My dog will be born with five fingers". However, I think your friend is using this sentence to humorously refer to the fact that she's having quintuplets! So, to answer your question, your friend is having five babies at the same time! Congratulations to your friend and her growing family!
