 The field source is a property that you can set for some field types in a data template, such as Droplink, Droptree, Multilist, Image, File, and so on. The field source specifies the location of the items or media that the user can select from when editing the field. For example, if you have a Droplink field that allows the user to choose a category for an item, you can set the field source to point to a folder that contains the category items.This way, the user will only see the relevant items in the drop-down list. The field source can be a path, a GUID, or a Sitecore query that returns a single item or a list of items. The field source helps you to control the data source and the user interface for the field. References:

This answer is based on the Sitecore documentation of dynamic placeholders1. Dynamic placeholders are an extension of the regular Sitecore placeholders that allow you to add the same placeholder name several times across multiple renderings, and even within the same rendering. Dynamic placeholders generate a unique key for each placeholder instance, which ensures that the content within the placeholder is unique and not duplicated. Dynamic placeholders also enable you to build functionality that generates multiple placeholders within the same rendering dynamically. For example, you can use dynamic placeholders to create a tab component that can have any number of tabs, each with its own content. References:

The $name token is a special token that can be used in fields on standard values items to instruct Sitecore to set the value of the field to the name of the item upon creation1. This token can be used in rich text, single-line text, and multi-line text fields2. To ensure that items created from a template automatically have the Title field populated with the name of the item, you should add the $name token to the template’s standard values Title field. This way, every item that inherits from the template will have the Title field set to the item name by default. You do not need to set the $name token in the new item’s content Title field, as this will only affect the specific item and not the template. The _name token is not a valid token in Sitecore and will not have any effect. References: 1: 2:
