r will it mess up traffic somehow if there are more than 1 way from
:switch A to C (once directly via cable and once via switch B)?

In order to prevent link problems, the feature you need to look for is
Spanning Tree.

A rule of thumb is that nearly all managed switches support Spanning Tree, and
most unmanaged switches do not.

The Netgear GS608 documentation makes no reference at all to supporting
Spanning Tree, so it probably does not support it.

The D-Link DGS-1005D manual mentions Spanning Tree (STP) in the glossary but
nowhere else, so it likely does not support it either.
