Just start the 3 nodes and keep all default settings regarding node roles.

So with 3 nodes, all them will be master, data, ingest.

As you are new, I suppose that you're using Elasticsearch latest version that creates one shard per index. That is enough as you'll certainly not have more than 2,147,483,519 documents on your shard.  
You don't have to have dedicated ingest node, as @dadoonet said, just let the default settings (all master, data and ingest).  
By growing in experience You'll certainly be able to define more precisely your needs.

**GET \_cat/shards?h=index,shard,prirep,state,unassigned.reason**  
Use this query to see what is the reason you have unassigned shards
