[Answered ]-Django display specific data from model in templates

In this case you should be able to say:

{% for e_field in exercise_all %}
<table>
<tr><th>Header</th></tr>
    {% for s_field in e_field.subject_set.all %}
    <tr><td>{{ e_field.name_e }}</td></tr>
    {% endfor %}
</table>
{% endfor %}
