Dear Aniket,
Good day! Thank you for posting in Microsoft Community. We are happy to help you.
From your description, it seems that you want to remove title column and add another title column in Microsoft lists.
If my understanding is right, we’d suggest you click the drop down arrow at the right side of Title column > Column settings > Show/hide columns, as shown below:
Then you can unselect it and click Apply. Then you can create a new column(for example, Title1)and put it at the top of the list, as shown below:
If the scenario above is not consistent with yours, you can also post back and point that.
