[Solved]-Highcharts format legend names-Highcharts

Use legend.labelFormat, for example: labelFormat: '{status}' demo: https://codepen.io/anon/pen/gKQxqo

Alternatively change status to name in your data options (default format for pie slice is {name}): https://codepen.io/anon/pen/gKQxEo

Second issue: it's hard to guess without live demo. You can work around the issue by setting plotOptions.pie.color. Just a guess, but maybe you have in your code Highcharts.setOptions() multiple times?
