1. 옆집 아줌마가 그것을 너에게 주라고 했어요 => OK, but 옆집 아줌마가 그것을/이것을 XX 씨한테 주라고 했어요 is better. 2. 옆집 아줌마가 그것을 너에게 달라고 했어요 => UNNATURAL. 3. 옆집 아줌마가 전해지 달라고 했어요 => 옆집 아줌마가 (이걸 / 이 말을) 전해 달라고 했어요. (The object may be omitted if it is obvious, as when you're showing it to the person) (Note that 너 can be very offensive if used with an adult who is not a close friend. If you're using the -요 form with someone, you absolutely cannot use 너. We say XX 씨, where XX is their name.) Sentence (2) is a tricky one to say correctly. Compare these two sentences which have different meanings. A. 옆집 아줌마가 XX 씨한테 그것을 달라고 했어요 = The lady next door wanted/demanded it from XX. B. 옆집 아줌마가 XX 씨한테서 그것을 갖다/받아다 달라고 했어요 = The lady next door asked me to get/fetch it from XX/you. In (B), the lady asked the speaker to go get it from XX. "to go get it from XX" is expressed as "갖다(가져다) 달라고" or "받아다 달라고". She asked the speaker, but the thing asked has two parts, "getting/receiving the thing from XX (XX 씨한테서 갖다/받아다) and giving it (달라고) to the lady". To spell out everything, it is like: 옆집 아줌마가 나한테 [XX 씨한테서 그걸 받아다] 달라고 했어요, but '나한테' is usually not included because it is obvious.
