Solving strange errors in the logs

Is any of this error important or unusual?

No, each one looks normal and none are dangerous. Several are caused by a program initializing prior to a needed service - for which the system will take correction action even if noting it in the log.
Several refer to a missing file, unsupported argument or missing element from ACPI table, but in each case it is not essential, has a fallback or is reporting on a missing file for logging, but the file is not supposed to be there. For example, many programs will check if a file exists, else perform a different action (or complete a staged action without concern of that files configuration settings).
Nothing there is cause for any concern.
