Is it too late to post bail after the arraignment?

My girlfriend has been incarcerated since may 24, she had 5 cases. On june 2 she was sentenced to 30 days as the final disposition for four of those cases but the court clerk says her sentence cannot go into effect until the last open case is heard. Her last case goes to arraignment in 9 days. i want to try and wait it out in case the judge releases her however, my question is...if the judge doesn't release her, will it be too late for me to post bail after the arraignment
