Answer 1

First of all You need to add column named "site_name" to your "report_list" table in database.
this query is for you to join 2 tables (here I took example "users" table as second table If your second table is defferent use your) ->
$records = DB::table('report_list')
->join('users', 'report_list.user_id', '=', 'users.id')
->where('report_list.site_name', '=', $site_name);
->select('users.*', 'report_list.email_date','report_list.url','report_list.recipient')
->get();
return view('monthlyReport')
->with(['records' => $records , 'site_name' => $site_name ]);

If you show the tables to see the columns and table names could help you better, while these are some examples:
//Option 1
$results = DB::table('users')
->join('business', 'users.id', '=', 'business.user_id')
->select('users.*', 'business.name', 'business.telephone', 'business.address')
->get();
//Option 2
$results = User::join("business as b","users.id","=","business.user_id")
->select(DB::raw("users.*"), "b.name as business_name", "b.telephone as business_telephone", "b.address as business_address")
->get();

Answer 3

You should create a model for your other table which I assume it's Site then in the report_list model create a relation method like :
public function sites(){
return $this->hasOne(Site::class);
}
or:
public function sites(){
return $this->hasOne('App\Models\Site);
}
After that in your eloquent query use this :
$records = DB::table('report_list')
->select('email_date','url','recipient')
->whereHas('sites', function($query){
$query->where('site_name',$site_name);
})
->with('sites')
->get();
