I think this will work.
var text value = List(" ; ",
ToText([Combined Text User in text format 1 ]),
ToText([Combined Text User in text format 2]),
ToText([Combined Text User in text format 3]),
ToText([Combined Text User in text format] 4));
ToUserList(
ToUser(Trim(Part($value,1,";"))),
ToUser(Trim(Part($value,2,";"))),
ToUser(Trim(Part($value,3,";"))),
ToUser(Trim(Part($value,4,";"))),
ToUser(Trim(Part($value,5,";"))),
ToUser(Trim(Part($value,6,";"))),
ToUser(Trim(Part($value,7,";"))),
ToUser(Trim(Part($value,8,";"))),
ToUser(Trim(Part($value,9,";"))),
ToUser(Trim(Part($value,10,";"))),
ToUser(Trim(Part($value,11,";"))),
ToUser(Trim(Part($value,12,";"))),
ToUser(Trim(Part($value,13,";"))),
ToUser(Trim(Part($value,14,";"))),
ToUser(Trim(Part($value,15,";"))),
ToUser(Trim(Part($value,16,";"))),
ToUser(Trim(Part($value,17,";"))),
ToUser(Trim(Part($value,18,";"))),
ToUser(Trim(Part($value,19,";"))),
ToUser(Trim(Part($value,20,";"))))
