UPFRONT CHANGING THE CONTACT FORM FIELD TEXT?

Hi, im using the Luke + Sara theme (upfront) with the contact form element, I wish to change the fields text + add additional fields is it possible to do this?

e.g. Change Subject text to Contact number. Change Description to Address + Add additional field such as Post Code etc.
