Pelipper is obviously one of the answers. Why Quagsire and Greninja do not qualify is because they are not available Pre-Bank. Ash-Greninja cannot breed. Surskit can evolve.
Q2:

Power Band was intentionally added as a diversion. It does not add Attack EVs at all. So the relevant calculation is:
Defeating a Pokémon that yields 1 EV
With Power Item + SOS Battle: 18 EVs
18 x 2 (I asked for 2 Mudbray) = 36 EVs.
Ok, made a mistake:
SOS + Pokerus = 1 x 2 (SOS) x 2 (Pkrs) = 4
4x2 = 8
Q3: Everything else with a TID not 'Alex' is a diversion. So are 90% of the details. Just zoom in to OT, TID and ESV.
- Toxapex, with OT: Alex, TID: 047867, is a self-caught, non-shiny Pokemon. Therefore, it being non-shiny indicates that 0465 is not the correct TSV.
- Meowth (Shiny), with OT: Alex, TID: 274568, is hatched by another Alex, as you can tell the TID is different.
- Popplio (Shiny), with OT: Alex, TID: 047867. It shares both OT and TID with the Toxapex and details listed at the top of the pastebin. Therefore, this is a Pokemon that has been TSV hatched by (the correct) Alex.
Ctrl-F Popplio's TSV, 2017, into the second sheet.
