1. 어쩔 줄 몰라하는 모습 Basically, 'A (form / figure) that I don't know.' 2. 사랑할래 Is like 'I will love' When made a statement or if in a question it's like 'Do you want to love?'. Then 사랑해요 in a sentence just means 'I love (person)'. As for three and four there are various ways you can translate it depending on what's before it. I see the sample sentence you posted but I'm getting hung up on the 봐라. Sorry~

또 봐라 봐줄때까지 널 사랑할래 I am going to take a chance in answering this for you. However, I am only taking a good guess from what I know. you should wait for a native speaker to answer this to get a better interpretation. 봐주다 in this case, I think it refers to the act of empathizing with others (putting yourself in their shoes) or overlooking their faults, etc... So what it means is that - if again you try as much as to be understanding, I will love you

3 & 4 the word stems 부르다 & 봐주다 both have various meanings so you need to provide context in which you found them to have precise translation
