         mlId: false,
         mlClass: 'bi-custom',
         mlDim: '200%',
         mlLabel: 'Milestone one',
         mlLabelVis: 'hover',
         mlHoverRange: 15,
         mlLineWidth: 1
       },
    2: {
        mlPos: 350, ---> (set $price value)
        mlId: false,
        mlClass: 'bi-custom',
        mlDim: '200%',
        mlLabel: 'Milestone two',
        mlLabelVis: 'hover',
        mlHoverRange: 15,
        mlLineWidth: 1
     },
     3: {
       mlPos: 400, ---> (set $price value)
       mlId: false,
       mlClass: 'bi-custom',
       mlDim: '200%',
       mlLabel: 'Milestone one',
       mlLabelVis: 'hover',
       mlHoverRange: 15,
       mlLineWidth: 1
     },
  4: {
      mlPos: 678,---> (set $price value)
      mlId: false,
      mlClass: 'bi-custom',
      mlDim: '200%',
      mlLabel: 'Milestone two',
      mlLabelVis: 'hover',
      mlHoverRange: 15,
      mlLineWidth: 1
    },
 5: {
     mlPos: 800,---> (set $price value)
     mlId: false,
     mlClass: 'bi-custom',
     mlDim: '200%',
     mlLabel: 'Milestone two',
     mlLabelVis: 'hover',
     mlHoverRange: 15,

Before you use json_encode cast the arrays into objects, you can also use JSON_FORCE_OBJECT option for that:

$prices = array( "250", "350", "400", "678", "800", "1000" );

$row = [
    'mlPos'         => null,
    'mlId'          => false,
    'mlClass'       => 'bi-custom',
    'mlDim'         => '200%',
    'mlLabel'       => 'Milestone two',
    'mlLabelVis'    => 'hover',
    'mlHoverRange'  => 15,
    'mlLineWidth'   => 1
];

$rows = [];
foreach( $prices as $price ) {
    $rows[] = (object) array_replace( $row, [ 'mlPos' => $price ] );
}

$opt = [ 'milestones' => (object) $rows ];


echo json_encode( $opt,  JSON_FORCE_OBJECT );

// output {"milestones":{"0":{"mlPos":"250","mlId":false,"mlClass":"bi-custom", ...
