Answer 1

Variables defined inside a for-loop are only known inside such loop. As you are trying to access my_total outside the loop u'd need to define it outside the loop, e.g.

{% set my_total = 0 %} {# <--- outside the loop #}

{% for product in products %}
    {% set my_total = my_total + product.total|replace({'AED': '', ',': ''}) %}
{% endfor %}

{% if my_total >= 500.00 %} {# <--- still accessible #}

    {% set randomPassword = [] %}
    {% set alpha = 'abcdefghijklmnopqrstuvwxyz' %}
    {% set numbers = '0123456789' %}

    {% for i in 1..10 %}
        {% set randomCharacter = random(alpha ~ alpha|upper ~ numbers ~ '-_') %}
        {% set randomPassword = randomPassword|merge([randomCharacter]) %}
    {% endfor %}

    {% set randomPassword = randomPassword|join %}
    {{ order_id }}{{ randomPassword }}
{% else %}
    (text)
{% endif %}

note: You should enable debug mode in order to see twig errors, when running your code you clearly get the following error

Variable "my_total" does not exist.
