Yes, you can charge different rates to different clients, however, there is not a way to specify this in your profile. If you would like to charge a client a different rate than what is posted in your profile, you will have to have that conversation with them prior to a booking. If you accept payment through the app, remind the parent to change the hourly rate as they are going through the payment process. It is easy for them to do so. On the confirmation screen after stopping the timer, they can edit your hourly rate.
