Are those apps with the cloud icon, rarely used apps? You may have Offload Unused apps set to ON. Either that or you may have just transferred or restored from a backup and the apps are not fully downloaded from the App Store.
What happens when you lightly tap on those apps? Do they begin loading? OR Do they just remain the same with the cloud to the right?
If nothing works then try a Force Restart on your iPhone.
Force restart iPhone 8
Press and hold both the volume down button and the Sleep/Wake button at the same time. When the Apple logo appears, release both buttons. (DO NOT release Side Button when invited to Slide Power OFF).
