I will assume that your $peoplehere variable equals something like the following...
<<set $peoplehere to ["Jane", "John", "Betty", "Bob"]>>
If I understand your question correctly you want to show a list of people names, each with an interage link that dynamically sends the reader to a Passage specifically associated with that person.
eg. Jane's interage link would send the reader to a Jane related passage, John's interage link would send the reader to a John related passage, and so forth.
I will assume that the person related passages are named something like
The following example should do what you want
A list of people.
<<for _person range $peoplehere>>
<br>_person <<link "interage" `_person + " interactions"`>><</link>>
1. I fixed the syntax errors in your <<for>> macro usage.
2. I replaced your Markup based link with the <<link>> macro so I could use backquote expression to dynamically generate the name of the Target Passage (based on the person's name and a " interactions" string).
3. I used a <<nobr>> macro combined with a HTML <br> element to better control where line-breaks were being inserted in the output.
