I have two forms/project on Kobo. How can I merge them together?

Welcome to the community, @SanjayMathew! Merging projects is not possible within the KoboToolbox system. Hence I have converted your post to features request (suggestion box). Maybe you could VOTE to make this a reality.

You could merge it outside the system and then upload the XLS data in the system through this python script:

Importing xls data into KoBoToolbox

@sareep, a while back have created a method for converting XLS data into XML with a Python script so that they can be submitted via the API. This requires an existing deployed form to be in your account. Everything is documented in this repository: https://github.com/kobotoolbox/xls-import. I hope this works for you.
