How to get latest entries, after X number?
In the way you have described that you want to use all the results on the page but just moved and used in chunks you should save a query on the database and use slice over offset.

{% set entriesList = craft.entries.section('news').limit(15) %}

{# Featured #}
{% for entries in entriesList | slice(0, 5) %}
{% endfor %}

{# Other List#}
{% for entries in entriesList | slice(4, 10) %}
{% endfor %}
