How much do they charge for transaction?

Basically MetaMask does not imply charges by using standard medium such as % of the fee transferred. Instead, it will charge by using “Gas” or “GWEI” , an internal currency commonly used for transaction for Ethereum. GWEI are commonly known as “small change” of 1ETH or 1e9.  The standard price for each transaction will be 21 GWEI , however users could choose to reduce the amount of GWEI required per transaction. But bear in mind that the lower the GWER , the higher possibility the transaction will fail.
