Is there any way through which I can control traffic from only few

For example, in an example configuration squid forwards traffic from

HTTP traffic from client C1 and C2<---> forwarding squid<---> P<--->
cloud
If parent P is down I want C1's traffic to be sent directly to the
internet by squid, while for C2 the connection should be dropped by
squid.
"prefer_direct off" affects traffics from all the clients.
Is there any way to use a combination of "prefer_direct off" and
"never_direct allow all/ always_direct deny all" ?
never_direct and allow_direct are lists with multiple lines performing
if-else logic just like http_access.
Think about it like this: you said you want these clients to go direct
*sometimes*, so why are you setting them to *never* go direct? ("all"
matches everything).
prefer_direct determins whether the parent or DIRECT are *tried* first.
First route to succeed suplies the answer.

i can think of a never direct and always direct and using an external
helper that will determine if the client will match the category of
never_direct or always_direct.
