Answer 1

I think the answer in the comments is what you are looking for: file.data = $file.data | ? id -ne 'Caption'.
To give a little explanation to this, it uses ? which is actually an alias (alternative name) for the Where-Object cmdlet, which is what you use when you want to filter a collection based on some criteria (very similar to the WHERE statement in SQL if you are familiar).
The above answer is a short version, you might alternatively see this:
$file = Get-Content '\path\to\file' -Raw | ConvertFrom-Json
$Result = $file.data | Where-Object {$_.id -ne 'Caption'}
Which is passing a ScriptBlock { } to the Where-Object cmdlet and using $_ to represent each item in the pipeline, then using -ne as the not equals comparison operator to see if the ID property of that object does not match the string Caption. If that is evaluated as true, then it allows the item to pass through the pipeline, which in the above example means it ends up in the $Result variable. If the statement evaluates as false, then it discards that item in the collection and moves on to the next.
