HOW? Conditional Statement and Custom Taxonomies

I have a page (single-portfolio.php) that displays each ‘portfolio’ custom post type. Within this post type I have 3 hierarchical taxonomies of ‘print’, ‘web’, and ‘identity’. I want to have a sidebar on this page that lists the recent posts for each taxonomy based on the taxonomy that is present on the page.

Does this make sense? I don’t know a lot of about how to write conditional statements, so I’m looking for some serious help here. Thanks in advance for anyone who knows how to do this and shares with me.
