If you are referring to the main record ID of anything within Salesforce, the answer is no, you can't change that ID, if you are talking about a custom field that you have marked it as external ID, yes, you can change that value as many times as you wish.
This "main" record ID I mention, is the ID you can see at the end of the URL of any record in your org.
