According to Tattvārtha Sūtra and Jain siddhānta, you do not meet your mother in Dev lok as a human family member.

Simple meaning

• In Dev gati, beings are born by karma.
• There is no human-style family life there like father, mother, husband, wife, children.
• So a mother in one birth does not remain “mother” in the same worldly sense in Dev lok.

Important Jain understanding

• The soul continues, but family relationships are temporary and belong to that particular birth.
• In Dev lok, a deva or devi may have karmic connection with other souls, but not ordinary family bonds like on earth.
• So you cannot think of it as: “I will meet my mother there and live together as family.”

About devis

Yes, devis are separate individual souls, just like devas are separate. But they are not organized as human families in Dev lok.

In short

No, not as a worldly mother-child family. At most, there may be karmic association, but not the same family relationship.

If you want, I can also explain this in simple Gujarati/Hindi according to Jain doctrine.
