Answer 1

awk 'NR==1{for(i=1;i<=NF;i++)n[i]=$i}; NR==3{for(i=1;i<=NF;i++){if($i~/florida|texas/)print $i"\t"n[i];}}' yourFile

see the test below:

kent$  echo "Ron Rob rock bammy
m f m f
florida Atlanta florida texas"|awk 'NR==1{for(i=1;i<=NF;i++)n[i]=$i}; NR==3{for(i=1;i<=NF;i++){if($i~/florida|texas/)print $i"\t"n[i];}}'

output

florida Ron
florida rock
texas   bammy

EDIT

kent$  echo "Ron  Rob  rock bammy
m    f   m  f
florida(8)  Atlanta  florida(8) texas(2;7)"|awk 'NR==1{for(i=1;i<=NF;i++)n[i]=$i}; NR==3{for(i=1;i<=NF;i++){if($i~/florida\(8\)|texas\(2;7\)/)print $i"\t"n[i];}}'

output:

florida(8)      Ron
florida(8)      rock
texas(2;7)      bammy
