As I have no idea which program you refer to ... still I would give it a statistic shot.
1. Probably there is only one option for percentage
2. You just place your banner taken from the affiliate program and place them on the site. They will contain your affiliate link.
3. The stats should be in the admin. I would use a program that does not have something like that as fraud can be made easily.
I can not see the option to allow fixed amount to affilliates
upto 5 referal get $50 etc
there is only percentage
secondly I am confused how to link affiliate link to my product
and how affilates can see my banners and links .
third if how to check reports of affiliates like how many clients are sent how many converted etc.
