in order of the pictures, they seem to be
1. S-71K "Carpet"
2. Not really able to find this thing's identification clearly
3. S-71M Monokhrome (this is the one that was a spotted carried by the aircraft externally sometime back)
4. S8000 Banderol , this is like the "low cost, long range" of the bunch, can be put in the same category as the anduril barracuda. and was already spotted on orion UAVs and as well as mi -28s before.
