I'll try and take a stab at this:
Green Star Polyps: Typically very fast growers. Smaller colonies can double size in a month, as colony size increases, the rate of doubling decreases, but they still grow fast. In a nano, any colony would be considered small. They will not overgrow any of the corals listed except maybe Xenia. Will be out-competed by euphillia genus corals, but probably work to a standstil with others. Were it my nano, I'd add them last as once estalished on rocks they're a pain to remove.
Pulsing xenia: If ideal conditions exist, they grow FAST. Can double in size in 2-4 weeks and spread like a weed. Occasionally, for reasons I can't figure out, sometimes they just don't grow. My own xenia colony took 1.5 years to double in size from one stalk to two. Then, bam, its growth rate exploded and I've had to trim them with a scalpel repeatedly. Likely killed by euphyllia, and possibly GSP, prolly will work to a standstill with others mentioned. Also of note, they can/will grow on your back walls. They can do it on glass, and will probably love that kind of substrate you have BigC. Somethin to think about.
Mushrooms: Depends on conditions/shroom. Actinodiscus species are probably the fastest growers and also most aggressive corals. In reproduction they often detach themselves from their rocks, and float to a more desireable location to grow. In your case, this can/will include your rock walls, so keep that in mind. Colonies can double in size in prolly 2 months IME. Rhodactus mushrooms are less aggressive and tend to grow slower, more like doubling every 4-6 months IME. They CAN float around the aquarium like actinodiscuss, but are not as prone to doing so as their cousins. Mushrooms may out-compete zoas, and will meet their demise at the hands of euphillia.
Zoos: Really depends on conditions. In high-light moderate flow, they can grow almoast as fast as GSP. Otherwise it may take many months to double in size. Typically larger-polyped zoas and palythoa that can be fed frozen foods grow faster than their small brethren. That way they're not very light-dependent. In your tank BigC, I'd expect a slower growth rate from smaller ones, and moderate growth rates from larger colonies if-fed. Will be held at-bay by euphyllia, and can be out-competed by mushrooms.
Ricordea: Grow the slowest of the mushrooms, prolly doubling in 6 months. They almoast never detach from their rocks. Like their mushroom cousins, will be killed by euphyllia and may out-compete zoas.
Torch/frogspawn/Hammer: The kings of the ring in this scenario, will kill all others. Hammer are usually the strongest of the three and CAN kill torch and frog, although sometimes they can co-exist. Frog and torch are usually fine with each other. Any of the three will kill all other corals in the list. Their growth rate is exceptionally variable. If chemistry is fantastic (high calc/alk/mg, no nitrate/phosphate) they can grow quickly, doubling every 3 months. Growth rates slow as the colony gets bigger/thicker but you won't really get to that size in a tank as small as yours. These corals can be fed frozen which will increase their growth rate. Lighting is also rate-limiting, but you have a decent amount, likely enough to prevent it from being rate-limiting. Chemistry and feeding will really help here. Presence of phosphates drastically stunts groth rate, even nearly halting it, so watch out for that. Mercifully easily fragged however in case the colony ever over-grows. Could be nice barriers to keep the softies from creeping on-to the walls if you want.
Hope that helped
