Answer 1

your code should be like this
public function staffHome()
{
$posts = Post::where('user_id', Auth::id())->latest()->paginate(5);
return view('staffHome', compact('posts'))->with('i', (request()->input('page', 1) - 1) * 5);
}

Answer 2

You can do it like this
$posts = Post::where('user_id', Auth::id())->latest()->paginate(5);
Where Auth::id() is currently logged in user's id.
Or with relation
Auth::user()->posts()->->latest()->paginate(5);

Answer 3

$posts = Post::where('user_id', $user_id)->latest()->paginate(5);
