Just open ur script editor in mIRC (alt+r or tools->script editor) then file->new, paste the script click OK and it'll work :>

where i need to put it in remote in alliases in popus? and how to add money to ppls or del or check the balance?

You have to put it in remote :)
I don't know about how to add money, but check the explenation of the script above, it's all explained there.
Note that the ! commands won't work from within your mIRC where you put the script in, you've to open a second client and execute the commands
