Yes postman can handle this call. But you will have to manually create the body which considering can contain 100 requests is going to be very time consuming and pron to error IMO.

As part of batch request, how batch request can be requested ?

By sending a HTTP Post where the body contains each of the single requests you are requesting data for.

how can I use batch request for above requirement endpoints?

You can do it with postman or any other programming language that can handle http post calls.

each line GET /farm/v1/animals in the body contains the request that you wish to make to the api in your case it would be something like users/me/messages/1.

You will need to call users messages.list first get a list of all the message ids that you want to get information for. Then build up your batch request to the user.messages to get and request each message. Batching will not mean that you dont need to send a get request for each message batching just saves you the extra http calls made by sending each get request.
