Create sObjects Dynamically in Apex

If you need to create record dynamically, then use below code:

For example, we are creating a contact record. 

String typeName="Contact";

Schema.SObjectType objToken = Schema.getGlobalDescribe().get(typeName);

sobject con= objToken.newSObject();

con.put("firstname","Sunil");  //first parameter is field API name and second is its value

con.put("LastName","Kumar");

con.put("Email","sunil02kumar@gmail.com");

insert con;

You can create any object record dynamically.

If you want to insert many records through list, you can store sObjects in list of sObjects and perform DML on list.
