... with both our parents and all of our non-identical twin siblings.

Cut that about in half for each subsequent generation -- 25% shared with grandparents and uncles / aunts, etc.

If you're asking for the amount of DNA shared with an uncle (a sperm-donating brother of the father), it will be 50% with him because he's the biological father. The "father" will instead be the biological uncle, sharing about 25% DNA with the child.
