Answer

If you mean Saudharm Dev, then in Jainism they do not have a human-style family in the ordinary sense. But Jain texts do describe the devas of the lower heavens as living with devangnas—their wives/consorts—and enjoying heavenly life somewhat like human beings. So the short answer is: yes, they can have consorts, but not a normal human family structure. ( jainpedia.org)

Explanation

Saudharma is one of the heavenly abodes in Jain cosmology, and the devas there belong to the class of Vaimānika gods. Jainpedia explains that in these heavens, pairs of gods and goddesses enjoy heavenly pleasures, and another Jain source specifically says that devas and devangnas “cohabit like human beings.” ( jainpedia.org)

Spiritual Understanding

In Jain Dharma, even heavenly beings are still within samsāra. They may have enjoyment and companionship, but they are not liberated souls. Their heavenly life is still temporary. ( jainpedia.org)

Takeaway

So, Saudharm Devs can have wives/consorts, but not a human family in the usual sense. If you want, I can also give you a very short English reference list from Jainpedia on this topic.
