#To associate them not needed:

• visibilty = not show inidividually
• stock = in stock
• price = also set
• status = enable

needed:

• attribute set = the same as configurable product

to create a config

Beside this you need to make sure, that the attributes you want to be configurable are NOT system, "Global", input type "Dropdown" and "allowed for configurables"

to show them in frontend

Only the simple ones which are in stock and enabled are shown in frontend, might be an indexing issue?
