At least one of these is not necessarily true. Others sound more like reworking the same conversion problem over and over.
Technically, there is no way to know (short of testing) how much DNA two siblings have in common. It could be 100% as identical twins have. It could be zero percent, though that is highly unlikely.
Each sibling gets 50% of their genetic material from either parent, but conceivably, two siblings could get different two dissimilar halves from each parent and be, effectively, unrelated genetically.
On average, more than likely, siblings share about half the same DNA.

Still, genetics is fascinating stuff.
