Answer 1

You can build your own custom filter
In the templatetags directory of your Django, add a file named 'mod.py'. In that file add the following code:
from django import template
register = template.Library()
def mod(value, arg):
if value % arg == 0:
return True
else:
return False
register.filter('mod', mod)
In your template use the mod filter like this:
...
{% load mod %}
...
<tr bgcolor="{% if forloop.counter|mod:2 %}#cccccc{% else %}#ffffff">
...

Answer 2

I think you want class='omega' on each 4th li of forloop. Use django Cycle in template in this way,
{% for story in data %}
<li {% cycle '' '' '' 'class="omega"' %}>
<div class="thumb">
<img src="{{ STATIC_URL }}images/thumb.jpg" width="185" height="185" />
</div>
<div class="thumbFooter">
<span class="view">
{{ story.views }}
</span>
<span class="like">
{{ story.likes }}
</span>
</div>
</li>
{% cycle '' '' '' '<div class="clear"></div>' %}
{% endfor %}

Answer 3

Or you could use the divisibleby filter. You can also use the add filter to adjust for all your conditions:
when forloop.counter%4==1 then this should be executed
{% if forloop.counter|add:"-1"|divisibleby:"4" %}
when forloop.counter%4==2 or 3 then this
{% if forloop.counter|add:"-2"|divisibleby:"4" or forloop.counter|add:"-3"|divisibleby:"4" %}
And without using add for the ones divisible by 4:
when forloop.counter%4==0 of for loop this should be executed
{% if forloop.counter|divisibleby:"4" %}
