Pregnant cat having trouble?

My friends 10 month old cat has been pushing and contracting for 3 days! Well he called me and my aunt over too his house and she had a kitten half way out for I don't know how many hours. We finally got it out around 3pm today! Well shes still been pushing and contracting all day here and doing nothing. We're almost 100% positive that all the kittens are dead but if we don't get them out we know she will die. Me nor the owners can afford a vet bill so please don't ask me to take her to the vet. I feel so bad for her and she's not even our cat! I'm an animal lover and doing everything I can to save her! Is there anything I can give her to help induce the labor or give her some energy! She won't eat or drink we have gave her some water with a medicine dropper! Please help me if she doesn't get any better I know we'll have to get her put down and she is an amazing cat and I just don't wanna see that happen to her! Thanks! Please be nice!
