Can we travel with her?

she in her applicant told that she listed us, but we will not go with her,now she want to get us with her

Answer 1

If she has already received her visa papers, then no, she can not add you. If she has not already received her visa papers, then she needs to phone Immigration and ask them what steps she needs to do in order to add you to her application.
Here's a link to the phone numbers:

Answer 2
