Are currency pairs related in some way?

After the US GDP release today the USD dropped against everything except the CAD, because the CAD released even worse economic data at the same time. The speed or reaction was interesting, the EUR/USD moved instantly, with the GDP/USD slightly behind, but the AUD/USD and NZD/USD were very slow to follow the direction, but did eventually. Is there money to be made in these delayed reactions?

No. Each one is a one-off.
 
Everything is correlated in FX. Just look at what happened when the SNB announced it would buy endless amounts of EURCHF at 1.20. EUR rallied and CHF fell almost 10% against all other currencies.
