These are correct use. "above" indicates the preceding concept or idea is more important than the following or in some way takes priority,
The old man is above ninety.
I am above forty.
These are not strictly correct, but are intelligible - English speakers will understand you but you will sound awkward.
Better are "The old man is older than ninety" and "I am older than forty". You can also use "over": "The old man is over ninety [years old]".
(Some people will say "better than" if they want to be careful about not invoking the stigma of age; you might see "for active adults better than 75 years of age" on a retirement home advertisement.)
