1 is normal and pretty much how all shimano bail wires are tapered, it's so when you close the bail and the line hits the wire it'll slide down to the line roller.
3 is normal as well from what I've seen, if set very light the clicker mechanism isn't full seated and won't racket aka make drag noise, also the vertical play of the spool is more significant with a loser drag setting but it's also inherent in reels with a worn drive gear train, it'll be like than on stellas,sustains,ci4s etc
(it's actually the vertical play of the main shaft due to the tolerances of the worn gear oscillation track which is purposely made a little lose so it functions smoothly, if they removed the "play" the reel would constantly bind on retrieve)
2 should be normal as well but I can't give it a 100% without the reel in hand but honestly pretty every reel has some of that type of noise
just curious how many or what other reels have you bought/owned? lol
