North and south on Cherry Court or east and west on Apple Avenue.

No, see solution.
Practice makes perfect
a
You both start your walk at the corner of Apple Avenue and Cherry Court. Therefore, the endpoint of both rays is at this corner.
Since you both walked in opposite directions, forming opposite rays, one of you could have walked north on Cherry Court and the other could have walked south.
You could also have walked along Apple Avenue, one going west and the other going east.
b
We know for sure that you and your friend walked in opposite directions. If you went east on Apple Avenue and your friend went north on Cherry Court, would you have walked in opposite directions?
East and north are not opposite directions. Knowing that you went in opposite directions, it is impossible that you went east on Apple Avenue and your friend went north on Cherry Court. Thus, your friend's claim is incorrect.
