Hi they are a bit blurry and therefore difficult to tell.
they look like amphipods such as gammarids but they tend to me aquatic species really. has the soil been waterlogged/suffered flooding from a river/stream?

welcome to GoY :o)

Beetle grubs of some kind? As Sbg says, a bit blurry to tell.

A clear photo would be useful. If you have a macro setting on your camera (indicated by a flower symbol), use it and try again.
