[Solved]-Highcharts separate datalabels per series-Highcharts

I know that its too late for answer but it can help to someone else.

You can do that by defining x value of each series's data label.

Here is the JS Fiddle:-

data: [{
  color: Highcharts.getOptions().colors[0],
  y: 100,
  name:'A',
  yAxis: 0,
  dataLabels: {
    enabled: true,
    style: {
        fontWeight: 'bold'
    },
    x: 60,
  },
},
{
  ...
}
]

You can format data labels for each series as in this example:

Setting series-level data label options

$(function () {
$('#container').highcharts({

    chart: {
        marginRight: 50
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, {
            dataLabels: {
                enabled: true,
                align: 'left',
                crop: false,
                style: {
                    fontWeight: 'bold'
                },
                x: 3,
                verticalAlign: 'middle'
            },
            y: 54.4
        }]
    }]

});
});
