There's no need for two pools. Drop the first (non-limiting) pool and
traffic that isn't shaped by the remaining pool will not be affected.
As for the second pool, since you only have a /24 network, there is no
need to use a class 3 pool. A class 2 will work just fine.

delay_pools 1
delay_class 1 2
#Bandwidth for this delay pool is 512 KB where each user can download at
a speed of 10 KB
delay_parameters 1 512000/512000 10000/512000
#limiting every user in the subnet 192.168.75.0/24 and allowing NoShape
and download acl to use the bandwidth freely
delay access 1 allow limitedto8 !NoShape !download
delay_access 1 deny all
