According to Minecraft, I now need at least Java 1.11 or newer (which is the best Java version?)
However, I also need Java 1.8 for older versions
1. Where can I download the Java versions safely and free of charge? I can't find the right link on java.com and oracle.com
2. How can I have two Java versions installed at the same time and possibly select the Java version for a Start.bat when I enter -jar in the console? Is that possible?
3. Can I destroy something with the update or should I just stay on Java 1.8 even if there's a warning?
I think you're throwing some things up…
Java Version! = Minecraft Version
Java or Oracle has nothing to do with Minecraft!
Minecraft versions are available on https://mcversions.net/
You can run all Minecraft versions with Java 8
Install Java 8 on Linux:
apt install openjdk8-jre-headless
(which is the best Java version?)
There's no "best" version. For most users, it is recommended that you use the latest version of LTS. This is currently the 11th
Where can I download the Java versions safely and free of charge?
https://adoptopenjdk.net/ or https://aws.amazon.com/de/corretto/ are good options. On Linux, however, you usually take the variant that can be found in the respective package repository of the distribution (apt / rpm / whatever) and don't have to worry about it any further.

You can have as many versions of Java as you want at the same time. Java doesn't actually have to be "installed" either - it is sufficient if it is unpacked somewhere on the disk. Which Java is used in the console depends on the shell settings (usually the first one found in the PATH). Otherwise you just have to explicitly specify the path to the desired Java.
No, the server software writes from 1.17 onwards, Java 11 is required. I have Java 8. What should I do now?

how does it work?

I meant on which page of java.com I can download Java 11 and the current Java 8
How does it work?
Well with the complete path. So instead of just typing "java", something like "C: \ programs \ dingsbums \ jdk-x \ java".

You don't need a "java.com page". You need a JDK binary distribution, and one of the things you can get one of these Under these links. There's no need to necessarily download a JDK from Oracle.
That's new to me…
What server software do you use?
Paper (advanced spigot)
A friend of mine has the same problem. But the message "only" says that this version is only a must from Minecraft version 1.17.
Are you on windows I have no problems with it on Linux. For Linux there are also simple apt repositories for Java 11, so there are no problems with Linux…
