How to find and use mesh positions in a variable for positions of other objects and generate them

I would like to know what the position of vertices in a mesh (but quadrants are more specific, and would be more helpful). Basically, what I want to do is have a sort of sphere, as created in Sebastian Lague's procedural planets, and find the positions of all quadrants to put a plane of noise onto it. This is his code that I used: using System.Collections; using System.Collections.Generic; using UnityEngine;

public class TerrainFace {

 Mesh mesh; //The mesh itself
 int resolution; //The resolution of the planet
 Vector3 localUp;
 Vector3 axisA; //Top and bottom of the mesh
 Vector3 axisB; // Sizes of the mesh

 public TerrainFace(Mesh mesh, int resolution, Vector3 localUp) //Generating the Terrain Faces, Uses variables Mesh, Resolution, Localup
 {
     this.mesh = mesh; //Sets the meshes globaly
     this.resolution = resolution; //
     this.localUp = localUp;//

     axisA = new Vector3(localUp.y, localUp.z, localUp.x); //Position of the Sphere/Cube's faces 

     axisB = Vector3.Cross(localUp, axisA); //Makes them Join
 }

 public void ConstructMesh() //Constructing the mesh
 {
     Vector3[] vertices = new Vector3[resolution * resolution];//Tells us how many verticies there are
     int[] triangles = new int[(resolution - 1) * (resolution - 1) * 6];//Tells us how many triangles there are
     int triIndex = 0; //Creates variable triIndex

     for (int y = 0; y < resolution; y++) //Tells us how big the y axis is
     {
         for (int x = 0; x < resolution; x++) //Tells the loop how big the x axis is
         {
             int i = x + y * resolution;
             Vector2 percent = new Vector2(x, y) / (resolution - 1);
             Vector3 pointOnUnitCube = localUp + (percent.x - .5f) * 2 * axisA + (percent.y - .5f) * 2 * axisB; //Defines the points where the angles generate
             Vector3 pointOnUnitSphere = pointOnUnitCube.normalized; //Makes the cube become a sphere
             vertices[i] = pointOnUnitSphere; //Part of making the cube a sphere

             if (x != resolution - 1 && y != resolution - 1) //Defines the triangles on the cube/sphere
             {
                 triangles[triIndex] = i;//Point one of the triangle
                 triangles[triIndex + 1] = i + resolution + 1; //Point 2 of the triangle
                 triangles[triIndex + 2] = i + resolution; //Point 3 of the triangle

                 triangles[triIndex + 3] = i;// Point one of the opposite triangle on the square of mesh
                 triangles[triIndex + 4] = i + 1;//repeated from above
                 triangles[triIndex + 5] = i + resolution + 1;
                 triIndex += 6;
             }
         }
     }
     mesh.Clear(); //Makes sure the existing mesh is cleared to reduce troubleshooting needed
     mesh.vertices = vertices; //Puts the verticies on the mesh
     mesh.triangles = triangles; //Puts the triangles into the mesh
     mesh.RecalculateNormals(); //smooths out lighting
 }

} How do I take the mesh out and apply those coordinates, angle, and rotation to a plane? I want to have a plane at each of the quads: https://imgur.com/a/r60FS78.
