No. You can't do that. eForms bot generates certain name for each input. However you can create as many forms you like on each language. Have you seen that documentation about:
http://wiki.elxis.org/wiki/Eforms ?
And one more question, how to change the format of the date, so it will have the format "dd/mm/yyyy)
File : mambots/content/eforms.php
Line : 676
Change the line :
if (($field->type == 'date') && ($field->default == '')) { $field->default = date('Y-m-d'); }to :
if (($field->type == 'date') && ($field->default == '')) { $field->default = date('d-m-Y'); }
