Unfortunately, the HP-25 has no insert/delete capabilities. The only way to do what you want would be to GTO nn (an unused program lline), then after the lines you want to insert, do GTO nn to go back to the line immediately after the first GTO. It's not efficient, but it does the job.
To "delete" a line, you can replace it to a NOP.
>What is the purpose of "suffix" key?
I think you meant PREFIX. If you mistakenly press any of the prefix keys (f, g, STO, RCL, GTO, whatever), you can press [f] [PREFIX} to cancel it.

Most likely the latter.
