JSON stands for JavaScript object notation. So, it's nothing but an object ( actually a subset of object ) in javascript.

So, actually you want to add an object in existing javascript object.

Also, jQuery is nothing but a library (collections of different javascript functions to ease selecting dom elements, ajax functions, and some other utilities)

Coming back to your question,

If this is your existing object,

var obj = {
    "188": {
        "Msg": [{
            "me": "hi"
        }, {
            "user": "hello"
        }, {
            "me": "ki chal riha hai"
        }]
    },
    "123": {
        "Msg": [{
            "me": "hi"
        }, {
            "user": "hello"
        }, {
            "me": "whtup"
        }]
    },
    "128": {
        "Msg": [{
            "me": "hi"
        }, {
            "user": "hello"
        }, {
            "me": "whtup"
        }]
    }
}

You can add

  var objToAdd =  {
            "Msg": [{
                "me": "hi"
            }, {
                "user": "hello"
            }, {
                "me": "whtup"
            }]
        }

by,

obj["128"] = objToAdd;

Now, your obj is,

{
        "188": {
            "Msg": [{
                "me": "hi"
            }, {
                "user": "hello"
            }, {
                "me": "ki chal riha hai"
            }]
        },
        "123": {
            "Msg": [{
                "me": "hi"
            }, {
                "user": "hello"
            }, {
                "me": "whtup"
            }]
        },
        "128":{
            "Msg": [{
                "me": "hi"
            }, {
                "user": "hello"
            }, {
                "me": "whtup"
            }]
        }
    }

Wouldn't that just replace the value for key "128" (as opposed to creating a duplicate entry for it, as you've shown)? — user2029783, Feb 11 '15 at 15:45
