This time, case 1 is the odd one out - but for that there is a thread in the FAQs:

> How to append the string " xyz" to the content of a tag field? Create a [new action](https://community.mp3tag.de/t/actions/967/2) in an existing action group and choose Format value as action type. Field specifies the tag field the formatting rule should be applied to. Format string must have the field placeholder for the field selected above and the string which should be appended. Example: If you want to append the string " xyz" to the current value of the comment field: Action type: Format value Field: COMMENT Format string: %com…

only replace the "xyz" with "ft %artist%".

Case 2&3 can be treated in 1 go:  
An Action of the type "Format value" for TITLE (or Convert\>Tag-Tag)  
Format string: `$regexp(%title%,(.*?) (\(.*\)),$1 (ft %artist%) $2)`
