Wrong in all three cases.

What you said is true if the runner is FORCED to advance when the batter becomes a B/R, but R2 isn't forced in any of those situations.

R1, R3, one out. Improper batter B7 receives a base on balls, on which ball 4 is a wild pitch. R1 advances to 2nd and R3 advances to the plate. Defense makes a proper appeal. B7 is out, R1 returns, R3 scores.

R1, R3, one out. Improper batter B7 swings and misses at an uncaught third strike, upon which R1 advances to 2nd and R3 advances to the plate. Defense makes a proper appeal. B7 is out, R1 remains at 2nd, R3 scores.
