This does 2 things; 1, tells you how powerful Return/Frustration is, and 2, some Pokemon evolve through max happiness after you level them up, so it tells you if that Pokemon would evolve.
It means thAt. That Pokemon is at maximum happiness and if youcan answer this , where can you find a happiny in any of the three Pokemon games ( platinum pearl or diamond )
If you mean they will gather in one inventory slot, then yes. They can go up to 999x. The Attack stat can be increased maxed to 100 EVs by using 10 Protein.
1.) If you mean just see for the national Dex there will be a trainer in Route 212 2.) If you want to catch one get an EEVEE from Bebe (In Hearthome City) and get his\her happiness maxed during the night.
