Using "Project Specific Select Field" plugin we can create new fields which can be editable by project administrators. Is there a way that I can make existing field editable ?
You mean existing custom fields?
If so, then no. Your existing fields are custom field types which are not provided by this plugin. You'd need to convert them to the new types.
