If these objects are lists, say list1 and list2, in your view just
create a single object made up of pairs of elements from the original lists:

values = zip(list1, list2)

Then you can pass that item to your template and iterate over it.

In older Django you would have to use dot notation to select the elements:

{% for x in VALUES %}
First item is x.0
Second item is x.1
{% endfor %}

I believe in more recent versions you have the option of unpacking the
two elements in the for statement:

{% for x1, x2 in lists %}
...
{% endfor %}

but don't take that as gospel until you've tried it.
