If you want to highlight by circles only then you can add css in code behind like below

if (e.Day.Date == dtFirstSchedule)
 {
    e.Cell.CssClass = "dotYellow";
    e.Day.IsSelectable = true;
 }
else if(e.Day.Date==dtSecondSchedule)
 {
   e.Cell.CssClass = "dotGreen";
   e.Day.IsSelectable = true;
 }
else if(e.Day.Date==dtThirdSchedule)
 {
    e.Cell.CssClass = "dotRed";
    e.Day.IsSelectable = true;
 }
else if(e.Day.Date==DateTime.Now.Date)
 {
   e.Cell.CssClass = "dotGreen";
    e.Day.IsSelectable = true;
 }
else
 {
  //do nothing
 }

And in css class add below css

<style>
        .dotRed {
            height: 25px;
            width: 25px;
            background-color:red;
            border-radius: 50%;
        }

       
        .dotGreen {
            height: 25px;
            width: 50px;
            background-color:green;
            border-radius: 100%;
            z-index:-1;
        }

        .dotYellow {
            height: 25px;
            width: 25px;
            background-color:yellow;
            border-radius: 50%;
        }
    </style>

This will display like below
