Answer 1

No, this isn't possible as the array technically won't be defined at that point.
One way to achieve this would be to use something like array_map.
http://php.net/manual/en/function.array-map.php
$recourd_list = array(
'clients'=> array(
'route' => 'clients.index',
'title' => 'fullname',
'list' => Clients::orderBy('id', 'desc')->take(5)->get(),
'count' => Clients::count(),
'class' => 'bgm-lightgreen',
),
'sliders'=> array(
'route' => 'sliders',
'title' => 'title',
'list' => Sliders::orderBy('id', 'desc')->take(5)->get(),
'count' => Sliders::count(),
'class' => 'bgm-rightBlue Oil-color',
),
'sponsors'=> array(
'route' => 'sponsors.index',
'title' => 'title',
'list' => Sponsors::orderBy('id', 'desc')->take(5)->get(),
'count' => Sponsors::count(),
'class' => 'bgm-nave dark-green',
),
'packages'=> array(
'route' => 'packages',
'title' => 'title',
'list' => Packages::orderBy('id', 'desc')->take(5)->get(),
'count' => Packages::count(),
'class' => 'bgm-bluegray',
),
'event_schedule'=> array(
'route' => 'event_schedule.index',
'title' => 'title',
'list' => EventSchedule::orderBy('id', 'desc')->take(5)->get(),
'count' => EventSchedule::count(),
'class' => 'bgm-orange',
),
);
then
return array_map(function ($item) {
$item['diff'] = $item['count'] - 5;
return $item;
}, $recourd_list);
Alternatively, you could use map with Collections
https://laravel.com/docs/5.3/collections#method-map
return collect($recourd_list)->map(function ($item) {
$item['diff'] = $item['count'] - 5;
return $item;
})->toArray();
Hope this helps!

short answer:
no.
But since you are, at init time, defining the Count, why not do this:
'diff' => 5 - Clients::count(),
so with the entire example:
return $recourd_list = array(
'clients' => array(
'route' => 'clients.index',
'title' => 'fullname',
'list' => Clients::orderBy('id', 'desc')->take(5)->get(),
'count' => Clients::count(),
'class' => 'bgm-lightgreen',
'diff' => 5 - Clients::count(),
),
'sliders' => array(
'route' => 'sliders',
'title' => 'title',
'list' => Sliders::orderBy('id', 'desc')->take(5)->get(),
'count' => Sliders::count(),
'class' => 'bgm-rightBlue Oil-color',
'diff' => 5 - Sliders::count(),
),
'sponsors' => array(
'route' => 'sponsors.index',
'title' => 'title',
'list' => Sponsors::orderBy('id', 'desc')->take(5)->get(),
'count' => Sponsors::count(),
'class' => 'bgm-nave dark-green',
'diff' => 5 - Sponsors::count(),
),
'packages' => array(
'route' => 'packages',
'title' => 'title',
'list' => Packages::orderBy('id', 'desc')->take(5)->get(),
'count' => Packages::count(),
'class' => 'bgm-bluegray',
'diff' => 5 - Packages::count(),
),
'event_schedule' => array(
'route' => 'event_schedule.index',
'title' => 'title',
'list' => EventSchedule::orderBy('id', 'desc')->take(5)->get(),
'count' => EventSchedule::count(),
'class' => 'bgm-orange',
'diff' => 5 - EventSchedule::count(),
),
);
