Question

If my search is scaled out like (Crawler on one server and indexer and query ) on other server, what are the services thats needs to be started the respective servers?

Answer 1

You should never be interacting with services.msc with regards to SharePoint Search (unless stopping it for patching purposes). If you deploy a particular Search role to a particular server, it will start the necessary services. There are only two Search services; the Host Controller service which monitors the SharePoint Search service.
