If you do not know how many instances you are going to create from the
beginning, there is no way for you to know which of the instances you mentioned
above will get created. So having names for all of the instances will not help
you since you will never know what names are "safe" to use.

On the other hand, if you have all instances in a list, you can refer to them
by index and you know exactly how many of them you have.

If you would like to get instances by some name you gave to them, maybe
something like this will work:

def get_instance(name):
    for instance in instance_list:
        if instance.name == name:
            return instance
    return None

Note that this might very well return None if no instance with that particular
name was found.
