       {
        "name":"happy",
        "age":38
      },

Just map the elements:

%dw 2.0
output application/json
---
payload.employees map {
    first: $.name,
    age: $.age
}

Output:

[
  {
    "first": "appy",
    "age": 34
  },
  {
    "first": "happy",
    "age": 38
  },
  {
    "first": "cruise",
    "age": 36
  }
]
