List Custom Tag Taxonomies in Post Meta – Single Post – Search Results

Hello. I’m developing a site and have created four custom tag taxonomies. I’d like to list them in the post meta, on search results, in the post archive, and on single post results. Obviously this will require some updates to the PHP. I’ve tried adding code to the .php, but it declares the custom taxonomy can’t be found.

How would I add the taxonomies to the single post template, such that a given post tagged with XYZ tags would have those listed, comma separated?

Thanks very much.
