Answer 1

In your upload method, you're missing the $plus variable
Change it to this
public function upload(Request $request)
{
$this->validate($request, [
'file' => [
'required',
'file',
'image',
'mimes:jpeg,png',
]
]);
if ($request->file('file')->isValid([])) {
$path = $request->file->store('public');
$filename = basename($path);
$plus = Posts::all();
return view('stories.index2', compact('filename','plus'));
} else {
return redirect()
->back()
->withInput()
->withErrors();
}
}

Answer 2

return view('stories.index2, [ 'plus' => Posts::all() ]); should work.
