If it's holding the soothe bell, about 2 hours
you have to get 212 Pokemon in that dex
it is faster to let it stay under a status are let it get knocked out a lot.
You cant unless you trade. It will take a long time
one week
If you are inhaling, not long enough.
battle with it enter in contest's that sort of thing it will take a lot of time but that's what you need to do
It depends on when the last fill up for the tick was. If it was recent it wouldn't take to long hanging on but if it had Waited for a long time it would cling on longer to fill up as it would think it would have to wait that long again...

Here's what you do: You always walk around with the pokemon, put them in easy battles, always use them in battle, and never let them faint. With Pokemon friendship in all Pokemon games, you must treat the Pokemon well for it to improve. In Pokemon Diamond and Pearl: Put the Pokemon in the front of your party Give it heal items when it is unwell and other items such as Carbos and Iron Use berries that promote friendship, such as Pomeg, Kelpsy, Qualot, Hondew, Greppa or Tamato Berries Take the Pokemon for massages in Veilstone or in the Resort Area's Ribbon Syndicate Level up the Pokemon and involve it in lots of battles Don't let the Pokemon faint or lose Let it hold an item - any item, but to promote friendship use a Soothe Bell These methods are sure to increase your Pokemon's friendship with you. Use the Poke App 'Friendship Checker' to check how the Pokemon feels towards you.
It depends on the pokemon; some pokemon are friendlier than others. To have the highest friendship with your pokemon, you need to win battles with it and carry it around in your party. To make this go even faster, you can make the pokemon the first one in your party and have it walk around with you. So, as it defers greatly, i would say that on average it takes around one and a half weeks (assuming you play thirty minutes to 2 hours on most days) I hope this helps! :)
