After doing some rolls:
Freighter 1:
1 out of 3 primary drive nodes can be repaired. The other two are FUBAR'd; this means that it's not hyper-capable, but it can (presumably) bring up the drive. 3 out of 6 secondary drive nodes can be repaired easily. It's going to have a very slow accel rate, even for MF's. Primary reactor mass is 92% depleted, with 50% left in the reaction thrusters, and approximately 70% of the contents have been looted. It has about 78/240 HP, and actually has breathable air in a few compartments, somehow.
Freighter 2:
1 primary node
might be able to be repaired, but not by what's being left behind and there's no way it can be fixed in time to make it to the mission. 2 secondary nodes can be repaired. The reactors have been ejected or stripped a long time ago, and the hull breached by a compensator spike ripping/melting a hole out of the backside and frying just about everything. Despite (or possibly because of) the massive damage, only 13% of the contents have been looted (probably because every door requires manual labor to open, and a few appear to have been rigged to explode outwards upon unsealing). It has approximately 20 HP left out of a presumed original 240 HP, and there is no way anyone would bother doing anything
but scrapping the ship.
Freighter 3:
There are no drive nodes left - someone else took them first. There's also no compensator, the bridge shows evidence of the chairs being removed, etc, etc. People have been stealing parts from this ship for a long time. Although it might, at one point, have been capable of being repaired, it's been so effectively looted that your time would be better spent building a new ship. The majority of the remaining cargo is classified as scrap and unrefined metal, with 87% being looted.
IC first post has been updated with the correct Fleet Sheet.
Amendment: Cossack has 70lm - base 30 plus 40 from sensors.
