Answer 1

You can easily define a toolip formatter for each series - see here: http://api.highcharts.com/highcharts/plotOptions.series.tooltip

{
  tooltip: {
          shared: true
  },
  series: {
     name: 'some series name',
     data: mydata,
     tooltip: {
        valueSuffix: ' bar'
     }
  }
}

Inside formatter this reffers to the focused serie, you can add an if/else inside the formatter and return a string for each one, like the following.

tooltip: {
    shared: false,
    formatter: function() {
        var text = '';
        if(this.series.name == 'MSFT') {
            text = this.x + ': ' + this.series.name +
                   '<br> $' + Highcharts.numberFormat(this.y, 0);
        } else {
            text = 'In ' + this.x + ' the median value was' + this.median +
                   'and the total $' + Highcharts.numberFormat(this.y, 0);
        }
        return text;
    }
}

Here's an example. The fiddle example is here:

tooltip: {
            formatter: function () {
                var s = '<b>' + Highcharts.dateFormat('%A, %b %e, %Y', this.x) + '</b>';

                $.each(this.points, function () {
                    s += '<br/>1 USD = ' + this.y + ' EUR';
                });

                return s;
            }
        },
