Is there another option to do it, or how do I know what packages use', I tried installing a few packages at one, but failed too.
The complete error is:

You have invalid YAML. A YAML list item is denoted by:
-<space><item>
Whereas you have:
-<item>
This is just a literal string. If you look at the error, you'll see the apt is trying to install packages with names like -unzip and -mysql-server, etc, which of course don't exist. You need to write your task like this:
- name: General | Instalacion de paquetes requeridos.
action: apt pkg={{ item }} state=present
with_items:
- unzip
- mysql-server
- mysql-client
- apache2
- php-mysql
- php-apc
- php-xmlrpc
- php-soap
- php-gd
- php
- python-mysqldb
But if you take another look at the error, you'll see:
Invoking "apt" only once while using a loop via squash_actions is deprecated...
It looks as if you've been learning Ansible based on outdated information. You should modernize your syntax to look like this:
- name: General | Instalacion de paquetes requeridos.
apt:
name: "{{ packages }}"
state: installed
vars:
packages:
- unzip
- mysql-server
- mysql-client
- apache2
- php-mysql
- php-apc
- php-xmlrpc
- php-soap
- php-gd
- php
- python-mysqldb
