Let me do you one better, by teaching you how to DIY any ship in EVE, fit for your specific needs.
Back in the day when I started, EVE had so many fewer ships available and not many of them were as useful, as they are now. So the few ships we did have, we used to fit for what we wanted to do, but back then, the Osprey for example used to be a mining boat.
Anyhow, by process of elimination, ask yourself what modules will be the most important to have to do x task?
Let’s take the Condor as your first example. The Condor has an inbuilt ship-bonus, that will make the task of pinning someone down much easier to do with an overall low skillpoint count.
In this case, I give you a general description of EVE terminology and two modules that do similar things, but for each case a little different, which gives you options and some hints for how to fly your ship, so you don’t get killed right after decloaking on a gate in lowsec.
The long point, or warp disruptor, is the long range version of the tool a Condor would be to have fit, to pin someone down. It requires a medium row slot.
The scram, or warp scrambler, is the short range version, which comes with a twist. The warp scrambler will shut off your opponent’s mwd or mjd in case of the command destroyer.
The Condor gives you a bonus, whenever you fly one, which allows you the use of a long point on a frigate. The long point is a nice module, but it requires a lot of cap(acitor) to run for long durations, and you wouldn’t want to fit one on a frigate or that one module would make your life very hard.
On the Condor, the ship bonus was given for the purpose of running a long point for long durations, plus all the other modules a Condor would need to fulfil that role.
With that in mind, we already have one of the four medium row slots filled with either a scram or a long point. However you decide, which module to take, it will require you to fly differently.
Another important module for any frigate or most would be the propulsion module, which will make your already fast ship even faster. In fact, you will be faster than most ships, which will be important, if you want to reach someone else’s ship, before they warp away.
Any Condor, or Crow, or Raptor build will use a mwd, or microwarpdrive. Just take my word for it. The mwd comes in three sizes, small, medium and large, so you don’t get confused which goes on which.
The Condor would fit a 5nm quadlif something mwd.
Now your specific purpose fit is ready. Those two modules are the most important ones and you always must fit them.
All the other available module and rig slots on the Condor fit go into defense, since you can rest assured, that people want to warp away and start shooting at you, and you want to make it as difficult as possible for that ship class to explode before the other one explodes.
Since the Condor is a small ship, most ships won’t bother shooting at you with medium or large guns, so they will send drones to do it for them.
Those drones are your biggest threat, so we will want to fit some kind of weapon to shoot those drones, whenever they threaten your existence.
I would recommend fitting 4x rocket launchers and take lots of Caldari Navy scourge rockets with you, so that 50% of your cargo hold it filled. You don’t want to run out of ammo while making sure, you keep that one ship on grid with your buddies and making sure, your ship stays intact as long as possible, so you only shoot drones that were sent to murder your ship.
If I recall correctly, the Condor has four medium row slots, of which two slot are reserved for a long point or a scram, which reminds me, you can fit both the disruptor and the scram on the Condor and a medium shield extender, which gives your ship some buffer to chew through for longer and shields regenerate in time on their own.
Now I am not sure, if the Condor also has two low row slots, in which case, you could fit a ballistic control and a damage control or a nanofiber propulsion upgrade, which makes the Condor even faster and more agile. A damage control would make you last longer. You decide, if you wanna go even faster or last longer, and I would suggest the latter and with experience, you can switch that in later builds.
The Crow and the Raptor are almost fit the same way, but the Raptor uses small railguns or blasters and would even be able to participate in shooting someone down, since the Raptor can do quite some damage.
The Flycatcher should now be much easier for you to fit. The most important module a Flycatcher would need in nullsec, would be the bubble launcher, which only the Flycatcher can fit, but the process is similar. However, in lowsec, I wouldn’t fly a Flycatcher, because no bubbles allowed in lowsec 
Happy hunting!
