Assuming that when you said:
Code:
file1.txt
No Match    chr1    35696    36106    DTE3504500000004
PXL-A0000005    chr1    69066    69311    DTE3504500000005

is what is in combine.txt, you really meant that the file you referred to as combine.txt is really named file1.txt (rather than the first line of combine.txt containing the line file1.txt, then maybe something like:
Code:
awk -F'\t' '
NR == FNR {
	r[$5] = $1
	next
}
FNR > 2 && m <= 0 && $5 in r {
	p = $5
	m = 2
}
m-- > 0 {
	if(r[p] == "No Match") 
		next
	gsub(p, r[p])
}
1' file1.txt output.txt > output.$$ && cp output.$$ output.txt && rm -f output.$$

will do what you want.

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk.
