Answer 1

Wrap that icon with Align and set alignment to centerRight , like this:

 IntrinsicHeight(
        child: Row(
          children: [
            Expanded(
              child: Column(
                children: [
                  Align(
                    alignment: Alignment.centerRight,
                    child: Icon(
                      Icons.info,
                      size: 20,
                    ),
                  ),
                  Icon(Icons.lock_clock),
                  Text('item 1'),
                ],
              ),
            ),
            VerticalDivider(
              color: Colors.black,
            ),
            Expanded(
              child: Column(
                children: [
                  Align(
                    alignment: Alignment.centerRight,
                    child: Icon(
                      Icons.info,
                      size: 20,
                    ),
                  ),
                  Icon(Icons.lock_clock),
                  Text('item 1'),
                ],
              ),
            ),
            VerticalDivider(
              color: Colors.black,
            ),
            Expanded(
              child: Column(
                children: [
                  Align(
                    alignment: Alignment.centerRight,
                    child: Icon(
                      Icons.info,
                      size: 20,
                    ),
                  ),
                  Icon(Icons.lock_clock),
                  Text('item 1'),
                ],
              ),
            ),
          ],
        ),
      )

Or If you want that icon attach to top right of column in overlay, you can wrap the column wit stack widget and set that icon in it, like this:

IntrinsicHeight(
            child: Row(
              children: [
                Expanded(
                  child: Stack(
                    alignment: Alignment.center,
                    children: [
                      Padding(
                        padding: const EdgeInsets.all(12.0),
                        child: Column(
                          children: [
                            Icon(Icons.lock_clock),
                            Text('item 1'),
                          ],
                        ),
                      ),
                      Positioned(
                        child: Icon(
                          Icons.info,
                          size: 20,
                        ),
                        top: 0,
                        right: 0,
                      )
                    ],
                  ),
                ),
                VerticalDivider(
                  color: Colors.black,
                ),
                Expanded(
                  child: Stack(
                    alignment: Alignment.center,
                    children: [
                      Padding(
                        padding: const EdgeInsets.all(12.0),
                        child: Column(
                          children: [
                            Icon(Icons.lock_clock),
                            Text('item 1'),
                          ],
                        ),
                      ),
                      Positioned(
                        child: Icon(
                          Icons.info,
                          size: 20,
                        ),
                        top: 0,
                        right: 0,
                      )
                    ],
                  ),
                ),
                VerticalDivider(
                  color: Colors.black,
                ),
                Expanded(
                  child: Stack(
                    alignment: Alignment.center,
                    children: [
                      Padding(
                        padding: const EdgeInsets.all(12.0),
                        child: Column(
                          children: [
                            Icon(Icons.lock_clock),
                            Text('item 1'),
                          ],
                        ),
                      ),
                      Positioned(
                        child: Icon(
                          Icons.info,
                          size: 20,
                        ),
                        top: 0,
                        right: 0,
                      )
                    ],
                  ),
                )
              ],
            ),
          )

This make icon closer to column.
