Depends on whether you are using
single function mode,
template program mode, or
general program mode. The first two require the braces. The third does not use braces.

ii) is "val" a general parameter to be replaced by something else;

Yes, but the replacement is automatic in single function mode. "Val" is replaced with the value of the field named before the colon. In the other two modes you must explicitly provide a value. This difference is discussed in the
template program mode documentation.

iii) in bulk edit search and replace does it go in the "search for:" section;

To use template functions in bulk search/replace, you must select "template" as the source field. A box will appear for you to enter the desired template. Any of the program modes can be used, although entering
general program mode templates into that box is a pain.
The search expression searches the result of evaluating the template.

iv) is the syntax different for the bulk edit approach compared to the template syntax when setting up a user-defined custom column with column type "Column build from other columns".

No, it isn't.

v) maybe seeing specific examples is the easiest way to see how it works?

You can see examples of using swap_around_comma in single function mode and template program mode in the thread containing
this post.
