You can use strcat so making a statement.

 

(setq lst '(123.45 678.99 100.34))
(alert (strcat "x= " (rtos (nth 0 lst) 2 2) "\ny= " (rtos (nth 1 lst) 2 2) "\nz= " (rtos (nth 2 lst) 2 2)))

Another to print individual items to the command line: 

(mapcar 'print '(1 2 3 4 5 6 7 8 9 "A" nil))

And for alerting individual lines:

(alert
  (apply 'strcat
	 (mapcar '(lambda (x) (strcat "\n" (vl-princ-to-string x))) '(1 2 3 4 5 6 7 8 9 "A" nil))
  )
)
