In this case, I feel like it, but in general, you'll get more answers
when you show some willingness to spend time on it.  Then it's more
fun to help others, because the questioner will appreciate the answer.

(defun foo (s)
  (interactive "sExtra string: ")
  (replace-regexp "abc" (concat "abc " s))
  (replace-regexp "def" "ghi")
  (replace-regexp "123" "456"))

It's possible that you have to add a statement (goto-char (point-min))
before each of the replace-regexp statements because replace-regexp
starts replacing at point, not at the beginning of the buffer.

Does this help?
