I got a new iPhone. How could I transfer all applications and others things from the old one.

See the options in Transfer data from your previous iOS or iPadOS device to your new iPhone or iPad - Apple Support

I recently used the Quick Start method described in that article and it worked very well.

Apps don't transfer between devices only app data gets transferred.

Stay connected to the internet and continue using the iPhone. Depending on the internet speed all apps will get downloaded from the App Store automatically. Apps don't transfer from iPhone to iPhone, only the app data along with app links to the App Store gets transferred.

Apps & Settings --> Apart from the Apps following will also not get transferred.

1. Content from the iTunes and App Stores or PDFs downloaded directly to Apple Books
2. Content synced from iTunes, like imported MP3s or CDs, videos, books, and photos
3. Data already stored in iCloud, like iCloud Photos, iMessages, and text (SMS) and multimedia (MMS) messages
4. Face ID or Touch ID settings
5. Apple Pay information and settings
6. Apple Mail data
7. Apple Music

All of the Apps on my old phone were automatically added to my new phone via the Quick Start method.
