profile.blade:

<table class="table table-bordered">
    <thead>
        <tr>
            <th>
                Name
            </th>
            <th>
                Email

        </tr>
    </thead>
    <tbody>
        @foreach($users as $usr)
        <tr>
            <td>
                {{$usr->name}}
            </td>
            <td>
                {{$usr->email}}
            </td>
        </tr>
        @endforeach
    </tbody>

Controller:

public function GetUserInfo($id){
    $user = DB::table('users')
        ->join('messages', 'messages.user_id', '=', 'users.id')
        ->where('users.id', '=', $id)
        ->get();
    if($user->count()){
        $user = $user->first();
        return view('profile')->with('users',$user);
    }
}

Model:

    class Messages extends Model
{
    protected $table = 'messages';
    protected $fillable = [
        'message','user_id'
    ];

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

In

    if($user->count()){
        $user = $user->first();
        return view('profile')->with('users',$user);
    }

first() is called on queries, but $user already exists as a Laravel collection by the time it enters the if statement. It should exist as an object or an array, and you can access it as such. Something like

if($user->count()){
        $user = $user[0]; /*OR*/
        $user = $user->0; 
        return view('profile')->with('users',$user);
}

I don't recall which is the right way off the top of my head. print_r($user) before to see what it looks like.
