I am in a group text and can see what everyone except 1 person is texting and she has an Iphone?

Send a group message with your iPhone, iPad, or iPod touch - Apple Support

If you can't send or receive messages on your iPhone, iPad, or iPod touch - Apple Support

send her these links, the issue is probably on her end, if you can see everyone else responses except hers.
