Hi, the last picture seems like normal shaped poop to me. What are you feeding them? Red foods like blood worms, krill flakes and etc can produce poop that is also red or orange. If more than one guppy is doiing it then high likelyhood is it's coming from something you're feeding especially if they are all acting/eating normally.

this happens when i don’t feed them. idk what they’re eating in the tank for their poop to look like this lol. it looks like a solid clump of worms. they only get baby brine shrimp and tubifex worms every other/few days.

Hmmm, probably still something they are eating but I'll tag @Colu and @Odd Duck

They probably need more variety in their diet than that.  I don’t see anything that convinces me there are parasites present.
