More than a couple dozen. Every cycle, one sovereign class reaper is created or so it's alluded, where as the amount of destroyers and other smaller ships is practically infinite.
The Leviathan of Dis is the first reaper found in the galaxy to date. The batarians took it and were indoctrinated. They estimated that it was a billion years old. Every 50,000 years the reapers would cull the advanced civilizations. Assuming they create one sovereign class reaper every cycle, that's at least 20,000 sovereign style reapers. This doesn't include the destroyers which number far greater.
So no, it's quite easy to see how a fleet would be decimated by them.
Also, every reaper that has been destroyed were the smaller destroyer type reapers, not the big ones.
Sovereign reaper = 2 kilometers (largest ship in the fleet was the destiny and it was still much smaller than sovereign )
Destroyer reaper = 160 meters.
Now compare that to the size of the alliance and alien fleets and you can easily tell why they were decimated.
Come on there isn't 20,000 soverign sized reapers or even limitless destroyers. If there was that many it wouldn't have taken "centuries" (We can assume it's more than 200 years) to kill off the Protheans. The codex says they only go for the largest cities and the most important systems. Maybe a couple dozen was low, maybe they're in the 100s, but there was probably only a few dozen at earth (15-20 on planet and another 20-40 in space) and then a thousand or so destroyers in space and land.
In game we don't see any capital ships get destroyed by Shepard, but in the codex it talks about it, the Miracle at Palevan, and in space you see dozens of destroyers being destroyed and possibly one or two soverign class reapers being destroyed. If you have a high EMS, though you are losing the ground battle, they heavily imply they're winning in space.
Not much is said outright, but they do mention several tiems that the reapers are taking heavy casualties, and I don't think they're referring to only ground troops.
Like I said before, the reapers were clearly massively outnumbered at Earth and they mention many times that the Reapers are their most strong at Earth (Reason they moved the Citadel there and not Palavan). They're not invincable, and they aren't infinate.
