Dark matter is thought to not interact with the electromagnetic force, could there be a force that does not interact with regular matter?

Also, could dark matter have different interactions with the strong and weak force?

Dark matter cannot interact via the strong force or the electromagnetic force.  It may or may not interact with the weak force, although many models have it doing so.

Yes, there could be additional forces that ordinary matter does not feel.  In fact, we already have examples of something like that, in that electrons do not feel the strong force.
