You need to build the arr of request to pass for forkjoin from your location id arr. I'm not sure this might work for you. try this and let me know.
import { Observable, forkJoin } from 'rxjs';
let location1 = this.http.get('http://192.168.7.45:9200/location/_doc/40871');
let location2 = this.http.get('http://192.168.7.45:9200/location/_doc/6009');

forkJoin([location1, location2]).subscribe(results => {
  // results[0] is location1 res
  // results[1] is location2 res

});

It's not correct to call API in the loop. It's difficult to handle the response of each request.

You have to use fork join.
