browser (IE) -> apache httpd proxy -> Proxy 1 -> target url
Proxy 2 -> target url
Proxy n -> target url
So basically I want to make my own apache httpd proxy that works as a loadbalancer between choosing external proxy setup'ed in httpd conf.
Current setup:
ProxyPreserveHost On
ProxyRequests On
ProxyVia On
ProxyRemote * http://proxy_ip:80
This version works nicely but I can't figure out how to add several proxy's to ProxyRemote? ... seems not working when setuping as: ProxyRemote * balancer://mycluster
Any ideas? Can it be achieved with apache or some other load balancer should be used?

Perhaps I'm a bit too late to help you, but it seems there is no clear answer elsewhere to your question, so this could be useful in the future.
Unfortunately the answer is you cannot achieve this kind of load balancing with Apache: as per the Apache documentation (https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxyremote) the ProxyRemote directive only supports http and https schemas, not balancer://
Cannot really figure out why the Apache developers didn't consider this configuration, tough, since I found a patch for mod_proxy.c (http://apache-http-server.18135.x6.nabble.com/attachment/4777809/0/ProxyRemote-Balancer.patch) which seems to do the trick by essentially just adding the balancer:// schema to the list of matched protocols.

Maybe it could work if you set up another vhost on the proxy server mapping to the balancer, then proxy to that vhost via
ProxyRemote * http://balancer-proxy.vhost.local
