General questions about replication

Hello everybody,

1. Can someone tell me if I can place a distributor on a SQL Server 2014 Standard Edition ?

2. Can my distributor be in SQL server 2016 version and my publisher and subscriber in SQL Server 2014 version ?

3. Can my subscriber be an Azure SQL instance. Here, it says that it's in preview, is that still the true ? https://azure.microsoft.com/en-us/blog/transactional-replication-to-azure-sql-db/

Thank you very much :)
