The 'pick nearest to' is not necessary as you already have the Family1 object picked from the 'On left button clicked' event.
To combine events 4 and 5 use 'or'

For your main question, you can use a third party plugin called 'nickname' and so create objects by name. You could also combine your sprites into one sprite and have different animation frames on that one object instead of different object types. That way you could 'create' the objects based on animation frame number.
