You do not need to open a separate Metamask for each friend. That would make Metamask nervous, with all the different passwords. Use ONE Metamask for all your accounts.

If you have an account, you can buy the SPURT Crypto and Inkagold, or if you work with someone else, they can send the Tokens to you.
You can also send Tokens to your other accounts.
See all the steps under "How to see your account in Metamask".

Get familiar with the system.

You go to the word Account, or if you have already changed the name, you go to that name and click on the arrow beside it.
Click on Add account or hardware wallet.

Now, you do not IMPORT an account; you create a NEW Ethereum account. Click on add account.

Go to the three dots and Account details. Change the name to the person you created the account for and check. Go back to Account details and see, at the bottom, copy address.
Click on the copy address sign and save the new address outside your computer.
Go to Show Private Key.
Enter the Metamask password and hold the blue button that shows your private key.

You know by now that this Key, in combination with the Address, gives you access to this specific account and everything on it. Therefore, save it outside your computer or mobile.

Now, you can use this address to fund your account yourself or provide the account address to others who want to provide you with any crypto they want.
To work with Binance, you must change the network from Ethereum, on the left, to Binance Smart Chain.

To check your account information in Binance, go to https://bscscan.com, enter your address, and see under Tokens how many different Tokens you have and what is on them. You can also see the contract addresses from the token provider.
