->where('student_id', '=', 2)->get();

Answer 1

Here is useful queries :
$today=DB::table('remaining_bus_fees')->whereRaw('Date(created_at) = CURDATE()')->where('student_id', 2)->get();
$yesterday= DB::table('remaining_bus_fees')->whereDate('created_at',Carbon::yesterday())->get();
$last_7_days= DB::table('remaining_bus_fees')->whereBetween('created_at', [Carbon::now()->startOfWeek(), Carbon::now()->endOfWeek()])->get();
$this_month=DB::table('remaining_bus_fees')->whereMonth('created_at',Carbon::now()->month)->whereYear('created_at', date('Y'))->where('student_id', 2)->get();
$last_month=DB::table('remaining_bus_fees')->whereMonth('created_at',Carbon::now()->subMonth()->format('m'))->whereYear('created_at', date('Y'))->where('student_id', 2)->get();

Answer 2

Change your code to this and it should work fine, you need to convert your Carbon::now() to date format as you will use whereDate here, it will consider only date.
$remain_fee = \DB::table('remaining_bus_fees')
->whereDate('date', '<', Carbon::now()->subMonth()->toDateString())
->where('student_id', '=', 2)->get();
Example in tinker
>>> App\User::whereDate('created_at', Carbon\Carbon::now()->subMonth()->toDateSt
ring())->get()
=> Illuminate\Database\Eloquent\Collection {#3120
all: [
App\User {#3114
id: 90,
name: "******",
email: "******#gmail.com",
created_at: "2019-05-01 06:17:47",
updated_at: "2019-05-02 00:28:18",
},
],
}
>>>

Try this out,
$remain_fee = \DB::table('remaining_bus_fees')
->whereMonth('date', '=', Carbon::now()->subMonth()->month)
->whereStudentId(2)->get();

Answer 4

At the minute your code is saying where date is "before a month ago" whereas it should be where the date is a month ago (i.e. remove <). Also, I would suggest adding the year to the query as well otherwise you'll start to get previous years results.
This should get you what you need:
$date = Carbon::now()->subMonth();
$remain_fee = \DB::table('remaining_bus_fees')
->whereMonth('date', $date->month)
->whereYear('date', $date->year)
->where('student_id', 2)
->get();
