Answer 1

Unfortunately by central admin UI you cannot change a web application name.
So there are two ways to do this
First as suggested above you have to delete web app and recreate again.
2nd one you can use powershell script to modify webapp name as below
$a=Get-SPWebApplication | where {$_.Name -match "Old web app name"}
$a.Name
$a.Name="New web app name"
$a.Update()
Get-SPWebApplication | where {$_.Name -match "New web app name"}
Hope that's helps you.
