Answer 1

Instead of trying to do some hack with angular you could use flexbox:

* {
  box-sizing: border-box;
}
.row {
  display: flex;
  flex-wrap: wrap;
}
.col {
  width: 50%;
  height: 40px;
  padding: 8px;
}

<div class="row">
  <div class="col">Col 1</div>
  <div class="col">Col 2</div>
  <div class="col">Col 3</div>
  <div class="col">Col 4</div>
  <div class="col">Col 5</div>
  <div class="col">Col 6</div>
</div>

It has the advantage that you can make a responsive design much easier than with a fixed number of columns with angular.

    <div class="row" ng-repeat="a in elem" ng-if="$even">
        <div class="col"> {{elem[$index - 1].name}} </div>
        <div class="col"> {{a.name}} </div>
    <div>
