For 5, since it doesn't say a word for it, and although it looks like a chili pepper, that could also just mean pepper in spanish which is pimienta, unlike chili pepper which is Aji picante (little dash on the I) Just to be safe since both Aji and pimienta has Aa, I would recommend choosing A.Aa. It could be other ones so im awfully sorry if its wrong. For 4, its a little bit confusing since that could mean several things from looking at the picture. If you believe its Indian, then in spanish it would be Indio, which could mean D.Ii. Just so I could help you further, is it asking for the first letters? Or the whole image? Hope this could help! I see how you could be confused by this. Tell me if anything. :)
