Answer 1

There are a lot of specific questions and answers at StackOverflow on how to merge(/join) a list of of objects in PowerShell.
Unfortunately, there is no native cmdlet solution in PowerShell that can do this "as fast and easy as possible", but there are a few cmdlets available for download as e.g. the Join-Object cmdlet at the PowerShell Gallery that can join object lists simular to SQL.

The required command for your question when using the Join-Object cmdlet will probably as simple as:

$ab = $a | Join $b Name
