Yes it's fine to run them simultaneously and yes that it happens in the "background" is normal as well. Wait for the mentioned time to pass then run smartctl -a on the drive. If you have trouble interpreting the outputs, post them here.

No the test is run by the device on itself so the tests will not interfere with each other. After the time has elapsed you can check the results with
# smartctl -a /dev/<device>

Looks to me like I should buy a new sdb and the other two are fine?
Now that I am reinstalling: I heard that brtfs should be better for / than ext4. What are the advantages/disadvantages?

1) where on earth did you hear this? The only reason I can't say it is complete nonsense is that it is too vague to pin down to any meaning at all.
2) btrfs has a lot of useful features, but in many ways it's still 'experimental'. Ext4 doesn't have as many features, but is much more well established.
3) What on earth does this have to do with this thread? If anything this question should be a separate thread, but even that I doubt as the way it's currently phrased is just bikeshedding.

https://www.smartmontools.org/wiki/BadBlockHowto might be able to force sdb to reallocate those sectors. If you are thinking of switching filesystems based on data check summing
I would consider zfs over btrfs but zfs is not without its disadvantages.
