Help! So for a reason I can’t specify, my family had to come stay with me (mom dad and sister). We are waiting on an answer from a job and then they will all move. They have been at my house for about 4 months and no one really knows when they will get the answer. Is it rude/bad child of me to set a boundary and have them make a plan of what they will be doing ?

Nope you should definitely set a boundary and ask them for a plan

I feel so bad

When we're trained to people-please and sacrifice for our families at all costs setting boundaries can come with a lot of guilt but it doesn't mean you shouldn't do it to protect yourself and your well being
