친구 doesn’t end in 받침(final consonant), so –

친구랑 (O) 친구이랑(X)

친구하고 (O)

친구와 (O) 친구과(X)

Since 공부하다(to study) is a specific action, it’s more natural to use 에서 to mark the place.

I’m going home means I’m headed to home, so 집”에” would be correct.

In this sentence, it’s implied that you “choose” what to buy. Since (으)로 can be used to mark what you choose, you can say 뭐”로” 사고 싶어요?

보다(to watch) is a specific action, so using “에서” sounds more natural to mark the place you did that action.

도 can be attached after other particles like 에서, 에, 한테, 에게, (이)랑, 하고, 와/과 etc, but it cannot be used with topic/subject/object particles.

When 도 is combined with other particles, they must be positioned after them.

place 에 있다: to be at place

place 이/가 있다: for there to be a place, to have a place

place 에서 있다 (X) : grammatically wrong

transportation (으)로: by (taking) transportation

(으)로 can also be used for directions.

왼쪽: left

엄마하고 옷이랑 신발을 샀어요. – I bought clothes and shoes (=옷이랑 신발) with mom (=엄마하고).

엄마하고 옷이랑 신발을 샀어요. – I bought clothes and shoes (=옷이랑 신발) with mom (=엄마하고).

으(로) can also mark the noun that serves as a “tool.” 핸드폰(cell phone) is a tool you used to make the video, so it can be marked 핸드폰”으로.”

내일에 집에서 잘 거예요. (X)
내일 집에서 잘 거예요 (O) – I will sleep at home tomorrow.

Words like 오늘(today), 어제(yesterday), 내일(tomorrow) cannot be marked with time particle “에.” It is used on its own.

Other choices :

월요일부터 금요일까지 일을 해요. – I work from Monday to Friday.

어제 동생이랑 집에 있었어요. – I was at home with my younger sibling.

많은 사람들이 파티에 참석했어요. – A lot of people participated in the party.
