After 70 or so posts here you should please be familiar with guidelines and be using dataex (SSC) to give data examples. See FAQ Advice #12.

For #4 consider this:

clear 
input str5 chid str2 mid str7 wanted 
"10143" "2"  "1014302"
"10145" "3"  "1014503"
"10146" "10" "1014610"
"10159" "15" "1015915"
end 

gen try1 = string(100 * real(chid) + real(mid)) 
gen try2 = chid + cond(length(mid) == 1, "0" + mid, mid) 

assert wanted == try1
assert wanted == try2 

list
