It seems like your friend has given birth to kittens, as she used the Filipino phrase "Ang pusa ko ay kakapanganak lang nang limang kuting." This translates to "My cat just gave birth to five kittens." So, in this case, your friend's cat had five kittens. If you're referring to human babies, there's no direct indication in the given sentence. To congratulate her, you can say "Congratulations on the new additions to your family!" or "Congrats on the adorable kittens!" if you want to focus on the kittens.
