Only one of the statutes in question mandates consecutive sentences, 1028A. The maximum sentence for these counts is 2 years for the crime charged. (He was not charged with a terrorism offense under 1028A, so the 5 year sentence is not applicable.) The way this statute is written, this 2 year sentence may not be concurrent to any other sentence for any other crime but multiple counts of the same crime can be served simultaneously. (Note that 1028A is an "enhancement" charge, similar to the gun enhancements I mentioned earlier. They are add-ons to other crimes, and cannot be charged separately. Basically, enhancement charges are used when additional circumstances covered by the enhancement make the underlying crime "worse" than a normal instance of that crime.)

1028 imposes a maximum sentence of 15 years for the gravest crime listed in the statute. Assuming he is found (or pleads guilty) this yields a likely maximum sentence of 17 years, or a potential maximum sentence of no more than 33 years.
