Nitro PDF uses the installed fonts in your system so if you want to type with certain fonts, then you need to install fonts using the default way. Simply, download the fonts package, unzip them if they are packed and go to Start > Run> Type "fonts (without the quotation marks) and paste the fonts in that folder then restart Nitro PDF again and use Text Tool to type something. From that point you should be able to choose the installed fonts using the drop-down menu for the font selection found in the upper left side of the software.
