GALACTIC REPUBLIC

In Attack of the Clones, we learn that Kaminoans have 200 000 clones ready, and million more on the way. Later it increases to maybe 5 000 000 clones.

SEPARATIST

„Our Droid armies outnumber the Republic clones a hundred to one“. – Dooku

From that, we can get 120 000 000 to 500 000 000 droids.

GALACTIC EMPIRE

Imperial Fleet has 26 000 ships of ISD-level equivalence. Let's assume that capital ships are equivalent to 25 000 ISD's (in both firepower and crew count) and that there are 150 000 fighters. ISD's volume is 11.9 times of volume of Galaxy class, according to Darkstar's volumetric page. With that, and assuming similar crew density, we can get 12 000 number for ISD's crew. That is 300 000 000 people for crew, plus 150 000 fighter pilots.

UFP

Starship crews
Galaxy – 1000
24th century Miranda class - 26 – 35.
Intrepid class - 141.
Average starship - ~200 (est.).

Considering that there are ~9 000 capital-grade starships in UFP, we could be looking at 1 800 000 to 3 600 000 people in crews of starships alone. Upper end number of 27 000 ships would give 5 400 000 to 10 800 000 people.

However, with Cardassia having 5 to 25 million men, and Klingon Empire 75 to 225 million, UFP should have 80 to 300 million men total.

CARDASSIA

Eleventh Order (reserve land unit) – 500 000
Unit under two Guls and Legate – 600 000
Both ground Orders; total of 12 Orders would result in number of 6 000 000 to 7 200 000 men.
If Cardassians had 5 000 ships, with 250 crewmembers per ship – 1 250 000 men in fleet; 15 000 ship fleet would have total creweng requirements of 3 750 000.
7 000 000 Cardassian soldiers died in a war (for comparation, USSR lost 9 000 000 soldiers in WW2 (6 300 000 KIA and 550 000 died from illness); at beginning of war they had 4,826,907  men and additionally conscripted  29,574,900 men). It means that Cardassian military is probably from 5 000 000 to 25 000 000 men.

KLINGON EMPIRE

1/3rd of Klingon military was enough to fight Cardassians to stalemate after they have recovered from initial strike and managed to mobilize. Klingons probably have around 7 000 capital ships and probably few thousand BoPs (say, 3 to 8 thousand); upper limit might be 21 000 capital-grade ships (BoP-size and above). However, due to

As for total forces, Klingons probably have 25 000 000 to 75 000 000 men, probably even more, considering fact that Cardassians were fighting defensive war; given that 1 : 3 ratio is generally required for attacker to defeat defending army, 25 to 75 million figure might simply be what Klingons threw into Cardassian space, for total of 75 to 225 million soldiers.

 

ROMULAN EMPIRE

While we don't have much data on Romulan Empire, it is considered to be one of 3 Alpha Quadrant superpowers, althought smallest of three. With that, and due to massive size of Warbird, and Warbird being just slightly weaker than Galaxy class, I would not give more than 1 000 to 2 500 capital ships in Romulan fleet, upper limit 3 000 to 7 500 Warbirds. Also, total manpower in military is probably similar to UFP and Klingon Empire, just slightly smaller, for total of 20 to 55 million men.
