OP, you should add Yellow Card Exchange to your list because that's the only exchange currently that their p2p trade in Naira is effective. The ones that you wrote in the list Binance and Kucoin no longer have Naira p2p.
Have not even heard about the Yellow card exchange which you mentioned before. Is the exchange a reputable one? and how do they operate? because I don’t really think it’s going to be a exchange like Binance, KuCoin and other reputable exchanges which we know.
KuCoin and Binance stopped their P2P operations in Nigeria when they started having problems with the Nigerian government. I think it was Binance that stopped there operation first, then follow by KuCoin, but we still have some popular exchanges that support P2P in Nigeria. The OP made a useful posts, at least we already know the exchanges that support P2P operations in Nigeria, we don’t have to be asking people, or start doing research to know the exchange which we can use to convert other currencies to Naira.
