Answer 1

Set up a relation from your Fund Model to the User Model

In your Fund model,

public function user()
{
    return $this->belongsTo('App\User', 'user_id'); 
}

and you could access the User that belongs to the fund as

$fund->user->{your-username-field}

OR if you don't want to set up a relationship and fetch the username, you could do so by

$user = \App\User::find($fund->user_id);
if (! empty($user)) {
    $user_name = $user->user_name; // or whatever the username field is
}

Answer 2

Try like this :

@foreach( \App\Fund::select("*")->with('users')->where('created_at', '>', \Carbon\Carbon::now()->subHours(24))->orderBy('id', 'DESC')->take(10)->get()->toArray() as $fund)
    <tr>
      <th scope="row"></th>
      <td>{{ $fund['user']['user_name'] }}</td>
       <td class="text-center text-warning">{{ $fund->total }}</td>
      <td class="text-right"><img src="https://adsok.com/img/btc.png" alt="Bitcoin"> <i><b>bitcoin</b></i><br></td><br>
    </tr>@endforeach

Answer 3

so you have to models: "Fund" and "User".
you should connect them with Laravel's Relationships:
add this method to "User" model:

public function funds()
{
    return $this->hasMany('App\Fund', 'user_id');
}

then in "Fund" model:

public function user()
{
    return $this->belongsTo('App\User', 'user_id');
}   

now you can access user's name from funds:
i suggest you to retrive your datas in controller, not views:

public function index()
{
    $funds = Fund::with('user')->
        where('created_at', '>', \Carbon\Carbon::now()->
            subHours(24))->orderBy('id', 'DESC')->take(10)->get();
    return view('viewName', ['funds' => $funds]);
}  

then in view:

@foreach ($funds as $fund)
    {{ $fund->user->name }}
@endforeach
