Do a girl's paternal uncles act as a barrier for her (i.e., should she observe hijab in front of them), and how is the inheritance divided between her, her full brother, and her full sister?

If the heirs are limited to those mentioned, the daughter receives half, as Allah Almighty says: "And if there be one daughter, she will have half." The remainder is divided between the full brother and his sister, with the male receiving the share of two females, as Allah Almighty says: "And if they be brothers and sisters, male and female, then for the male will be the share of two females."

The inheritance is divided into six shares: three for the daughter, two for the full brother, and one for the full sister. The daughter does not exclude her paternal uncles; rather, they are excluded by the presence of a closer male agnate to the deceased. It is advisable to refer inheritance matters to the Sharia courts to ensure the rights of heirs, creditors, and legatees.
