How do I use timers and variables to control several instances of sprites?

I am trying to make a simple platform test and create a bunch of enemies that share the same sprite, but have their own variables control them. I am assuming timers is the way to go but I have tried a few things and have not been able to figure it out-

a quick example- all same sprite enemies but with different "walking" paths with different duration's / distances

I am using bullet and bullet speed / time to move them back and forth now

is there an easy way to do this I am just missing? I am pretty sure im close but I am just not getting it...

There are many ways you could do it, here's one

I'm using Platform Behaviour instead of Bullet to clip the Enemies nicely to the Ground with their Gravity plus you have more control to do more things like Jumping etc....
