I've recently listened to a couple of songs and found a common beat. A quick google search for their genre shows that they fall under the umbrella of Hip-Hop/Rap. However, searching for 'Hip-Hop/Rap' doesn't result in a songs with the same beat; I thought that there might be a more specific term for them. Here are the songs :
I would say mostly downtempo then chillout

I believe the term would be trap music.
Trap is a subgenre of hip hop music that originated in the Southern United States during the early 1990s. The genre gets its name from the Atlanta slang word "trap," which refers to a place in which drugs are sold illegally. Trap music uses synthesized drums and is characterized by complicated hi-hat patterns, tuned kick drums with a long decay (originally from the Roland TR-808 drum machine), atmospheric synths and lyrical content that often focuses on drug use and urban violence.It utilizes very few instruments and focuses almost exclusively on snare drums and double- or triple-timed hi-hats. This is the signature sound of trap music.

Trap is one of the most popular modern sub-genres of rap. You can tell it by the distinctive ultra-fast beat that is present in your sample songs.
