Help ID these small creatures please

I don't mind having these guys in my tank but I'm wondering if any of these will be a threat to shrimps and snails.

Creature #1: Largest one, about 3mm


Creature #2: Looks like a dot and moves fast


Creature #3: I thought it was the same thing as #2 but lacks the tail (?) in closer inspection


Creature #4: Looks similar to #1 but much smaller


Creature #5


#1 and #4 looks like detritus worms but just in case they are planaria, some advice from people with first hand experience will be great. I personally don't see the triangular head though.

Thanks a lot.

Perfect thanks. I'll let my shrimps coexist with these guys.
