What to do with multiple transformation matrices?

Question

OpenGL

Hello! Let's say that I have several objects on the stage and I need them all (or only a few) to somehow transform (someone moved, moved, etc.), therefore, each of those who move / move / scale should have a transformation matrix, but what about her?
Now the vertex shader code (there is only one object and one transformation matrix on the stage) looks like this

#version 330
layout (location = 0) in vec3 position;

// выход на вход в фрагментный шейдер
// Приписка 'pass_' для моего удобства
in vec2 uv;
out vec2 pass_uv;

//матрицы
uniform mat4 ModelMatrix;
uniform mat4 ViewMatrix;
uniform mat4 projectionMatrix;

void main() {
 
  gl_Position = projectionMatrix * ViewMatrix * ModelMatrix * vec4(position, 1.0f);

  pass_uv = uv;
}

Please tell me what should be done (with what to multiply, where and how) with the transformation matrices (which are responsible for the transformation of these very few objects)?
