entourage
A group of people who accompany or support someone; their following. It can sometimes have a slightly derogatory meaning.

The pop star never traveled without his large entourage of stylists and assistants.
The word is derived from the verb 'anhängen' (to attach). An 'Anhang' (attachment / appendix / entourage) is therefore literally something that is 'angehängt' (attached) to something else. This logic applies to email attachments, appendices in books, and also groups of people.
Bitte hängen Sie die Dokumente als PDF an.
Please attach the documents as a PDF.
The context reveals the meaning. If it is about emails or letters, it refers to a file. In books or reports, it is the final section. If people are being discussed, it means their entourage or following.
Die Datei ist zu groß für den Anhang.
The file is too large for the attachment.
When referring to an email attachment or a book appendix, the preposition 'in' with the dative is almost always used to describe where the information is located: 'im Anhang' (in the attachment / in the appendix).
Im Anhang dieser E-Mail befindet sich das Protokoll der Sitzung.
The minutes of the meeting are in the attachment to this email.
When 'Anhang' (entourage) is used for a group of people, it can have a slightly negative or ironic undertone. It implies that the people are not independent and merely follow along.
Der Chef kam mit seinem gesamten Anhang zur Firmenfeier.
The boss came to the company party with his entire entourage.
