cacheClientHttpRequests is not a global counter, it is a per client
counter in the cacheClientTable. You can use this to plot the number of
requests from a specific client by encoding the client IP address into the
SNMP object ID if you like.

cacheProtoClientHttpRequests is the numer of requests received by your
proxy on it's http_port (and http_ports if any).

cacheServerRequests is the number of requests sent out by any protocol,
i.e. cache misses, but also including retried requests.
