It is! :-)

Yes, they are all similar but have a different focus.

  - show-paren-mode flashes "the other" paren, i.e., the opening when
    you are on the closing one.
  - rainbow-delimiters colorizes all parens (and brackets, braces) in a
    different color based on their depth.
  - highlight-parentheses is basically like rainbow-delimiters, i.e., it
    also colorizes parentheses (and brackets, braces) based on their
    depth but only the ones surrounding/containing point.

So you could view highlight-parentheses as a cross-breed of
rainbow-delimiters and show-paren-mode.  Just that it's actually a bit
older than rainbow-delimiters.

Indeed, but one doesn't change names after more than 13 years of
existence and establishing a user-base.  But I hope that it's
description "Highlight surrounding parentheses" describes it pretty
clear in the `list-packages' listing.
