Hur was the father of Uri, and Uri was the father of Bezalel.
Caleb here is plainly a shortened form, so all exegetes recognize it. The first half of verse eighteen is obscure and likely corrupt in the text. We must read it as 'Caleb begat with Azubah' and separately 'with Jerioth', one was his wife, the other a secondary partner, and only one wife's sons are listed before her death in verse nineteen.

Atarah was Jerahmeel's second wife, distinct from the first; the phrase 'another woman' can mean concubine, though wife seems more likely here. She bore him Onam, and likely he was her only son to Jerahmeel, whose other descendants are named elsewhere in the genealogy.
AI summary
The text about Caleb appears tangled in our version: he is called father of Hur in one place and son of Hur in another. The latter passage has been copied wrong and should read 'Hur the son of Caleb.' Azubah was his wife; Jerioth was a secondary wife, mother of those children named.
