Try changing your CompanyName field to:

"CompanyNameId": {
    "__metadata": {
        "type": "Collection(Edm.Int32)"
    "results": [ 2 ] // Array of the IDs of your selected items

Since per your comment your data format is set, why not just transform it before sending your update?

var data = {"Address":"","CompanyName":[{"ID":2,"Title":"InfoEngg"}],"Email":"[email protected]","Title":"Kapil","Mobileno":"9898989898","Password":"Sp@12345","EmpRole":"Level 1"};

var updateData = {
  Address: data.Address,
  CompanyNameId: {
    "__metadata": {
      "type": "Collection(Edm.Int32)"
    "results": $.map(data.CompanyName, function(c) { return c.ID; })
  Email: data.Email,
  Title: data.Title,
  Mobileno: data.Mobileno,
  Password: data.Password,
  EmpRole: data.EmpRole

    Well, you asked why you're getting an error, and that's why. The service is expecting CompanyNameId and it's not there. :)
