Would it be possible to make a planet orbit a star, and five moons
orbiting the star with the planet, one in each Lagrangian point?
Or even the moons orbiting the Lagrangian points themselves (ie.
seemingly orbiting around nothing.)

Only if the moons have a small enough mass (compared to the two others).
That's the definition of the Lagrange points. Is an asteroid a moon ?
Problem with L1, L2 & L3, they are a saddle: along the orbits, the field
push you back to Lx, but along the star-planet line, the field push you
away from it, so if you get nearer or further, you're doomed.
The asteroids (trojans and greeks) at L4 & L5 of the sun-jupiter system
shows that it's possible to have some swarms moving around the sun at
the rate of the planet.

Relatively stable system with two planets. Green's orbit is way too
wobbly to sustain life, but life on Blue could potentially exist,
albeit, with Game-Of-Thrones-like seasons that last for years.

Haven't been successful so far. Probably because of the limits of the tool.

Haven't been succesful either.

I made the Suns a little less wobbly and the planetary orbits are a bit more
stable too

And now woth binary planets:

This is actually a lot of fun

The Green planets collide after 10 minutes or so.
This one, though, appears very stable.

Yes.

Now with a 3rd planet. Unfortunately, with the tool's granularity, I
can't make it a binary planet. :(

Ok.. . Now I should stop playing with this and do actual work...
