Maybe someone more familiar can help, but it looks to me like the first two you posted are Etherium (or ERC20 token) addresses, not bitcoin addresses. You can't convert an Etherium address to a Bitcoin address, it's two different block chains.

Just because a string starts with "0x" doesn't mean it is a shitcoin token. 0x is the prefix used to indicate the encoding of the numbers that follow is hexadecimal. Similarly 0b indicates binary. History.

In this case the hexadecimal values represses a public key (the first one which is 33 bytes and starts with 03) and the private key (the second one which is 32 bytes) that generated that public key.
