good morning

To set up Bedrock Edition on your Nintendo Switch for free after purchasing Java Edition in January 2022, you will need to follow these steps:

Log in to your Mojang account on the official Minecraft website.

Go to your account settings and look for the "Claim your free copy of Minecraft" option.

Select the "Redeem" button next to the Nintendo Switch option.

You will be prompted to enter your Nintendo Switch account details.

Once you have entered your Nintendo Switch account details, the Bedrock Edition will be added to your account.

Go to the Nintendo eShop on your Switch and search for "Minecraft."

Download and install the Bedrock Edition of Minecraft.

To be able to have one account for both Nintendo Switch and PC you will need to have the Windows 10 edition of the game on the PC. As Java and Bedrock (Xbox One, mobile, windows 10, nintendo switch) has different coding in the game.

Hi, yes and yes. Bedrock edition on Windows is commonly known as "Minecraft for windows"
About your last question, yes. Your child can play with people from Xbox, PS, Nintendo Switch and mobile using the Minecraft for windows / Bedrock edition .

As long as the other friend is not using the Java edition, you're good to go. If that's the case your child needs to open the Java edition

Hope everything is more clear now, but if you have further questions feel free to ask

You wont be able to transfer packs between Java Edition and Bedrock Edition ( Windows 10, Xbox One, Mobile, Nintendo Switch) as they use different coding to make the game.
