can i stop them or allow to run them only after when i want to run them. means when i want only that time those run otherwise not.
how i can remove them from startup
You can see all your SQL server instances from the Sql Server Configuration Manager if you have it. There you can set the startmode to Manual instead of Automatic. This can also be done from the services console as arunkumar said. The service should be named SQL Server (SQLEXPRESS).
