The word "old " can get two meanings:an old man or a human, who is more years old, than u." Old man" or "Older man" are different things. We use older, when we say about man,who is more years old among others or among group. We use elder, when we say about,example,our brother,who is more years old than u. We say"Elder brother". I`m not sure, have i answererd right or had a mistake?
