‘Replacement transaction underpriced’

Your provided wallet address is associated with two network, one is ETH while other is BNB. You have ETH and other erc20 tokens which you can send to any other wallet. Perhaps you customise the fees , I suggest you to choose recommended fee and it will go through.
Coming to Bnb network it has very low balance but still you can send that small amount of bnb available there. Again choose the recommended fee and not to customise it.
