What to pair with these 4*bot?

I am a new player (less than a week) and have gotten my 4-star batch including 1) Coelgon 2) 2) Long haul 3) Scourge and 4) Cicadagon. May i have advice which bot should they pair with? I have Acid storm to go with Cicadagon, but can’t find mate for the rest. Thanks.
