It's sort of a multi-verse, like some have said already. Some games share world names, but not always the "world" itself. Like FFVII and FFIX both take place on Gaia, however, the two Gaia are different. FF Tactics and FFXII both take place in Ivalice, though there was some talk if I remember correctly that they were same world, just 1,000 years apart. FFX took place in Spira. FFXI was on Vana'diel. FFXIII is Gran Pulse (iirc). FFXIV's world is named Hydaelyn.
Dimension hopping between them all seems possible given the Lightning events where FFXIII's main character came to Eorzea. Shantotto from FFXI's Vana'diel also crossed into Hydaelyn briefly by some fluke of magic. Also, Atomos in the XIV and XI universe is a dimension hopping/folding void creature who ventures into worlds shortly before some calamitous event and consumes their lifeforce/aether/mako/lifestream whatever.
In short, the lore of FFXIV's world, Hydaelyn, is its own and not tied to any of the previous games by anything other than coincidence and familiarity. Several elements from the series are present in most all of the games but in most cases the lore behind each world is unique to the individual game.
Hope this helps! ^^
