1- What’s the Difference between BEP-2 and ERC-20?
2- How BEP20 works
3- For High Gas Fees They doing this?
4- BEP-2 address also similar as ERC20 Address why?
1 and 2 - BEP-2 is binance chain. Blockchain launched by crypto exchange. It is less decentralized than ETH (ERC-20), thus is able to provide better bandwidth. ETH is POW BNB is DPOS and proof of authority -

4- Binnance aimed to do a chain that is compatible with ETH to use infrastructure that is being build for ETH for last 5 years (f.e. you can use metamask to hold/transfer binance chain coins). Everything you can do with ETH you can do with binance chain too because of that. IF you are developer you can move your project from ETH to Binance chain without extra coding.
would add that ETH-20 is a protocol for fungible tokens on Ethereum network and BEP-2 is a protocol for fungible tokens on Binance chain, Binance is providing a lot of incentive to project for a transition to Binance chain from Ethereum blockchain, and uses funds to fund their development in case of transition, but the biggest different, crypto wise, is that Binance chain is centralized and owned by Binance, and Ethereum chain is a pretty decentralized network, even after PoS transition that should happen in two years or so
