See the Lambda Expressions node of the Emacs Lisp manual.

If you don't know how many there are, you can't name them individually.
(defun your-function (&rest argument-list)
(interactive
(let* ((n (read (read-from-minibuffer "How many arguments? ")))
(i 0)
(args '()))
(while (< i n)
(setq args
(cons (read-from-minibuffer (format "Argument %d: "
(setq i (1+ i))))
args)))
args))
...)
