Can I call a tile that was discarded earlier, or only the most recent one?
Only the most recent one. A discard can be called while its window is open, and the window closes the moment the next player draws and racks or discards. After that the tile is dead, and so is every tile that went into the center before it. Nobody may call a dead tile, for an exposure or for Mahjong.

One live tile at a time
At any moment there is at most one tile in the center that anyone may claim: the one just thrown. Any player except the person who threw it may call it, to complete a pung, a kong, a quint or a sextet in an exposed hand, or as the fourteenth tile for Mahjong.
Everything else on the table is history. The tile you let pass three turns ago, the one you only now realize you needed, is dead, and it stays dead for the rest of the hand. Regret is permitted. Reaching for it is not.
When the window closes
A discard stays callable until one of three things happens. The player to the discarder's right draws a tile and racks it or discards. Another player begins a Joker exchange. Or someone declares Mahjong. Any one of those closes the window, and the tile joins the dead.
Notice what does not close it. A player merely touching the wall, or lifting a tile and holding it, has not racked. Racked means the tile is sitting on the bottom ledge of the rack and leaning against the back with the others. Until then, a call on the discard is still in time.
The same tile twice
Now and then a tile is thrown, and the very next player throws its twin before anyone speaks. A call at that point takes the second one. The first went dead the moment the second landed, because only the most recent discard is ever live.
So if you wanted that tile, you have not lost your chance. You have simply been handed it again, by someone else.
After Mahjong, nothing
Once a player has declared Mahjong and shown the hand, the game is over. No earlier discard may be called for anything, however neatly it would have finished your own hand. And a discarded Joker is dead the moment it lands, most recent or not. It can never be called at all.
How to never miss one
The rule is strict, so the habit has to be quick. Before each discard lands, know which tiles your hand still wants. When one appears, call it plainly: call, or take, is enough. If you need a moment to decide, say wait so the table pauses, and then decide promptly.
And keep an eye on the pile for a different reason. Every dead tile tells you how many of its kind are left in play, which is information you can use for the rest of the hand.
