These numbers look like they belong to the B.
The A has bigger internal weapons bay and is cleaner and lighter than B, so better acceleration and speed. Also better agility and (for whatever reason) a higher structural G limit.
As for a 5th gen definition, how about this one:
The exact characteristics of fifth-generation jet fighters are controversial and vague, with Lockheed Martin defining them as having all-aspect stealth even when armed, low probability of intercept radar (LPIR), high-performance airframes, advanced avionics features, and highly integrated computer systems capable of networking with other elements within the battlespace for situational awareness.
Using this definition, it would appear only the F-22 and F-35 qualify in the west.
And my understanding is that the new generation Russian/Indian and Chinese fighters don't have all-aspect stealth. I have no idea about their avionics fit or their networking capability.
