6 Rich Text Field and 1 Toolbar with JS for new question page -- 2

Hi, I am developing examination application. On the adding question page I need rich text editor for adding question. User should have capabilities like that adding mathematical formulas, scienfitic formulas, images, tables, aligning text, paragraph, inserting images.... There should be one toolbar for 6 textfield. If you click one textfield you can use toolbar for that textfield. You can see my design, there are 5 text field and one toolbar. Thank you...
