Здесь всё и так переведено, я отметила только какие прямые, а какие косвенные. 
Прямую речь от косвенной можно отличить тем, что прямая - это речь какого-нибудь лица, передаваемая без изменений. На письме она заключается в кавычки. 
А косвенная речь передает слова говорящего не точь-в-точь, а лишь по содержанию, в виде дополнительного придаточного предложения.
