I've looked at the half sibling and full sibling part. If I bring the full sibling definition into the half sibling definition then it would read:

Half- siblings only share one biological parent instead of two as full siblibngs do.

But I have found a different link that explains more or less every type of sibling with adoption included: http://siblings.askdefine.com/

This would mean that Angela and Henry are half siblings.

If Jake hadn't adopted Henry then would they be step siblings? Also as it hasn't been mentioned if Addison adopted Angela, let us assume she hasn't, would that make her Angela's step mum?
