1. **Saan ka pupunta?
"Nasaan" is used for asking the current location of something/someone.
** and since the question is an actor focus, the answer should be in actor focus as well, so
"Pupunta ako sa tindahan." would be the correct answer and not "pupuntahan ko ang tindahan."
2. Sino (ang) **tinulungan niya?
** Ang tinulungan niya ay si Robert. / Ang tinulungan niya ay ako.
(the verb should be in "completed aspect" or the close equivalent in English would be "past tense", based on the translations you have provided.)
3. Sino (ang) tumulong kay Robert/sa akin?
** Siya (ang) tumulong kay Robert.
** Siya (ang) tumulong sa akin.
("siya" should be located at first or if we'll use the "ay" sentence, it should be located at the end,
like: "Ang tumulong sa'kin ay siya."
but the most common is "Siya ang tumulong..." which is a direct answer and you can actually drop the following sentences unless you want to give an emphasis. unlike the "ay" sentence, it gives a bit of suspense; and like the direct approach, from "ay" going backwards can be omitted as well.)
** Tumulong siya kay Robert/ sa akin. is like a plain declarative form. unless the question is
"Ano ang ginawa niya? (What did she do?)" then
"Tumulong siya kay Robert/ sa akin" would be the correct answer 🙂👍🏼
I hope it helps somehow 😊
