How can I create multiple questions on a page

You may try a 'Multi-line Question' field type to be able to add up to 8 inputs on a single page.

If this is not enough, you may consider trying a classic form layout where you can add unlimited fields per a form page. To do this, switch to the 'All Questions in One Page' form layout via account settings, then create a new form.
