They are all correct -- except 4 which should be
I have to wash my face and brush my teeth.
The answers you provided are all grammatically correct. However, they seem to be in the form of a list rather than answering the question "What do you have to do before you go to bed?" directly. If you want to rephrase your answers to directly answer the question, you can say:
1. Before going to bed, I have to vacuum the floor of my bedroom.
2. Before going to bed, I have to make the bed.
3. Before going to bed, I have to take out blankets and a pillow from the wardrobe.
4. Before going to bed, I have to wash my face and brush my teeth.
5. Before going to bed, I have to close all the windows and clean my bedroom.
6. Before going to bed, I have to write in my diary.
7. Before going to bed, I have to do my homework.
8. Before going to bed, I have to say good night to my parents.
I hope this helps! If you have any further questions, feel free to ask.
