well ishida's quincy powers are neither death god nor hollow.
chad's are definitely hollow.
orihime's, who knows. although they resemble kidou and somewhere in the ss arc i remember someone saying she will probably become a powerful shinigami when she dies.



edit: turns out the orihime comment was made later during the arrancar arc (by ukitake while watching her train with rukia). episode 138 and in the manga (chapter 230) the line is a little different (seems to include all the humans, not just orihime).
