You can use custom validator. Check the documentation. You can get messages from $errors variable in blade template.

$validator = Validator::make($request->all(), [
    'title' => 'required|unique:posts|max:255',
    'body' => 'required',
], [
    'title.required' => 'Title required custom message',
    'title.unique' => 'Title unique custom message',
    // ...
]);

if ($validator->fails()) {
    return redirect()->back()
                ->withErrors($validator)
                ->withInput();
}

If you want to send redirect with data. You can use

redirect()->route('route')->with('data', 'test');

You can get after redirect

session('data')
