        "short_name": "Engelsa street",
        "types": [
          "route"

Answer 1

You can search the address components array for some element entry that has a types array with every value you want it to contain.

obj.address_components.some(({ types }) =>
  types.every((type) => [/* list of keys */].includes(type))
);

const obj = {
    address_components: [
      {
        long_name: "10",
        short_name: "100",
        types: ["street_number"]
      },
      {
        long_name: "Engelsa street",
        short_name: "Engelsa street",
        types: ["route"]
      },
      {
        long_name: "Saint-Petersburg",
        short_name: "SPB",
        types: ["locality", "political"]
      },
      {
        long_name: "Russia",
        short_name: "RU",
        types: ["country", "political"]
      },
      {
        long_name: "194017",
        short_name: "194017",
        types: ["postal_code"]
      }
    ],
    formatted_address: "Engelsa street, 100, Saint-Petersburg, Russia, 194017"
  };

const res = obj.address_components.some(({ types }) => types.every(type => ['country', 'locality'].includes(type)));
const res2 = obj.address_components.some(({ types }) => types.every(type => ['country', 'political'].includes(type)));

console.log("'country', 'locality'", res);
console.log("'country', 'political'", res2);
