The only time your matrix has any effect is when you call glDrawArrays/glDrawElements or one of their similar derivatives.

The way to draw multiple objects, each with their own matrix would be similar to the following pseudocode:

foreach (Object obj in List<Object>) {
    setupVertexAttributes(obj.attributes);   //setup the attributes (VBOs)
    uploadMatrix(obj.matrix);                //set the matrix
    glDrawElements(obj.indices);             //draw the object

}
