How to align names?For example: front position, back name

Just 2 para styles and 2 Grep Find/Replace!

(^/)  The Jedi

I would recommend using tabs. Create a paragraph style for this text, then in the options for it, go to Tabs. There you can set places for where you want each name to line up. The example I set up for you below shows the first tab as being right aligned (look very closely at the top of the arrow shortly before the 6) and the second one being left aligned (currently hightlighed in blue because it's selected). So you will need to put a tab character in before the first name and between the first name and the second name to get them to line up at the tab stops you created. You can drag and drop these tab stops to modify them, but I find it easier to do once you have your text on the page and can watch it move. If you want to have dots going between them, that's what the Leader box is for. You can just do a "." or you can do " ." (space then period) to have it spaced out more, etc.

Hope this helps!

If you are looking for scripting help, try this below sample snippet:

var myDoc = app.documents[0];
var textFrame = myDoc.pages[0].textFrames[0];
app.findGrepPreferences = NothingEnum.nothing;
app.changeGrepPreferences = NothingEnum.nothing;
app.findChangeGrepOptions.includeFootnotes = false;
app.findChangeGrepOptions.includeHiddenLayers = false;
app.findChangeGrepOptions.includeLockedLayersForFind = true;
app.findChangeGrepOptions.includeLockedStoriesForFind = true;
app.findChangeGrepOptions.includeMasterPages = false;
app.findGrepPreferences.findWhat = "~>~>";
var allEnSpace = textFrame.insertionPoints[0].parent.findGrep();
var maximumHorizontalDistance = null;
for(var i = 0; i < allEnSpace.length; i++){
    if(maximumHorizontalDistance == null){
        maximumHorizontalDistance = allEnSpace[i].insertionPoints[0].horizontalOffset;
        }
    else if(maximumHorizontalDistance < allEnSpace[i].insertionPoints[0].horizontalOffset){
        maximumHorizontalDistance = allEnSpace[i].insertionPoints[0].horizontalOffset;
        }
    }
for(var i = 0; i < allEnSpace.length; i++){
    var tempPara = allEnSpace[i].paragraphs[0];
    while(maximumHorizontalDistance > allEnSpace[i].insertionPoints[0].horizontalOffset){
        var characterLength = allEnSpace[i].insertionPoints[0].index - tempPara.characters[0].index;
        var leftSpace = maximumHorizontalDistance - allEnSpace[i].insertionPoints[0].horizontalOffset;
        var defaultSpace = allEnSpace[i].insertionPoints[0].paragraphs[0].characters[0].insertionPoints[-1].kerningValue;
        for(var c = tempPara.characters[0].index; c < allEnSpace[i].insertionPoints[0].index-1; c++){
            allEnSpace[i].insertionPoints[0].parent.characters[c].select();
            allEnSpace[i].insertionPoints[0].parent.characters[c].insertionPoints[-1].kerningValue = parseInt(defaultSpace+10);
            myDoc.recompose();
            }
        }
    }
