Good, you have only 8 cards, and still you are looking to cut down. Congrats.
As per me, you can close the following cards -
1. Scapia - I don't know why you are keeping this
2. ICICI Sapphiro - It is mostly useless (except BOGO BMS)
3. Amex Plat Travel - If your spends are less using this card.
4. Two cards from these 4: ICICI Amazon Pay, HDFC Swiggy, SBI cashback, HSBC Live+
(Basically all these 4 are almost similar types of cashback cards.)
HDFC Swiggy gives 5% on Amazon, Flipkart, Ola, Myntra and some other places and 10% on Swiggy.
SBI CB 5% on all online, HSBC Live+ 10% on grocery, Apay 5% on amazon spends. Depending on your usage, you can think of closing one or two. Having all 4 of them is an overkill). If it was me, I would close SBI CB and ICICI Apay.
