Yeah MC2 is based on a very specific point in 616. At some point the Hand became REALLY interested in making him work for them, and I think that's the same story line where they got together.
Interestingly, part of the backstory for Rina is that she learned to focus her powers by training with Psylocke, and that's why her claws look vaguely similar to Psylocke's psi weapons.
Yeah, Felicia married and then divorced Flash and was living with her girlfriend (pretty sure they'd retcon that to wife now). And this was before Kevin Smith's reference to it in 616.
And I'm pretty sure good Kaine was in MC2 long before 616. (I only leave that open because of some reading gaps.)

Interesting that you mention Anya, because despite her appearing after the divergence point she also exists in the MC2. In fact, so do other characters such as Maria Hill because there is nothing to rule out any of the characters you mentioned existing in the MC2, it's just that they have yet to appear. As for Anya being pushed as Spider-Girl, that's really more of a case of in-house nepotism on the part of Joe Quesada et al because she keeps being used in marketing despite her own ongoings tanking fairly quickly. Also, Anya worked far better as a Latina hero called Araña than as a cookie cutter generic hero trading on Mayday's nom de guerre. It's a disservice to both characters.
This is something people have been perpetuating online for a while now. It's based on a single panel of a single issue having a newspaper which featured the year 2017 and another issue showing 1996. These are nothing more than the letterer making an in-joke or a topical reference. Further, there are more examples that no one seems to mention, such as Last Hero Standing where a newspaper gives the date as 2015. I wouldn't read too much into it.
