Answer 1

Only the type for interface needs to be done, as you have. The fields will be (id, date) instead of mine in the interface:
service:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Todo } from './app.interface';

@Injectable()
export class AppService {
    constructor(private httpClient: HttpClient) {}
    
    fetchDataApi(url) {
        return this.httpClient.get<Todo>(url)
    }
}

component:

import { Component } from '@angular/core';
import { AppService } from './app.service';
import { Todo } from './app.interface';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  public users: Todo;

  constructor(private httpService: AppService) {}

  ngOnInit() {
    this.loadData();
  }

  loadData() {
    const API_URL = 'https://jsonplaceholder.typicode.com/todos/';
    
    this.httpService.fetchDataApi(API_URL)
      .subscribe(data => {
        this.users = data
      })
  }
}

interface:

export interface Todo {
    userId: number,
    id: number,
    title: string,
    completed: boolean,
}

Very strange statement of a question, but I will try to poke.
in $orders you have an array with objects?
Get them somehow (ngrx, etc.)

orders = [
{id:1,date:"22.02.2020"},
{id:2,date:"22.03.2020"},
{id:3,date:"22.04.2020"}
]

<tr *ngFor="let order of orders">
<td>{{order.id}}</td>
<td>{{order.date}}</td>
</tr>

If you have never worked with Angular, then there is no simple answer that you can copy-paste into your project.
If with English norms, I advise you to start with the official tutorial https://angular.io/tutorial , it understands how to display data on the page and how to get it from the server.
