Can you have multiple form elements?
There is no reason why you can't have multiple forms on a single page. You just can't nest forms, because then the forms aren't able to identify which fields are for what.
How do you make a form more interesting?
Integrating animation, fewer words, and graphical design are the visual elements you may want to focus on to make your form more fun. For written content, make it short and sweet. Your customers will want the form to be as easy as possible to read and complete.
