Question on enforcement- new series or not.

Team has runs off tackle for 4 yards on 2nd and 10 from Team B's 20 yard line. After the play B92 pushes A32 from behind and A34 retailiates by shoving B92.

Two personal fouls are called and because they are dead are administered in the order of their occurence. The first will take the ball to the B8 yard line, then it will be moved back to the B23 yard line.

Does Team A get a first down here because they were ahead of the chains during the markoff.

What if the first penalty had been live ball followed by a second dead ball on the defense.
