Installing an indexer is the same as installing a search head.  Once installed, go to Settings->Forwarding and Receiving on the indexer to enable reception of data on port 9997.  Then go to Settings->Distributed Search on the search head to connect the SH to the indexer.

TBH, what you're asking for here is the topic of a week-long Splunk course (and a certification exam) so it's too much to cover in an Answer.  However, each of the instances in your question is covered by at least one manual at docs.splunk.com.

Installing a forwarder is very similar to installing Splunk Enterprise, but with a different binary.  You'll need to modify the forwarder's outputs.conf file to point to your indexer(s).

Splunk management node don't receive syslog.  They only manage other Splunk instances.  To receive syslog, use a dedicated syslog server such as syslog-ng to write the events to files which are monitored by a forwarder.

And if you expect to ingest more than 500MB a day you'll need a license.  Install the license on the SH or management node and point the indexer(s) to that instance (Settings->Licensing->Change to peer.

I'm sure you'll have more questions as you go.  Feel free to come back with more specific questions when you get stuck.
