You've answered your own question about what it is.

You have oniguruma5 installed and are now trying to install oniguruma6, and you can't do that because they conflict.

Since you are asking about it, I assume you did not deliberately install oniguruma but that it was installed for you as a dependency of another port, and that that other port has switched from 5 to 6 since the last time you updated. You may need to deactivate oniguruma5 to proceed with the upgrade, assuming it is not needed by any other ports. See https://trac.macports.org/ticket/60788.

Don't know. Just because oniguruma advertises that it offers a feature does not mean that no other software also offers that feature.
