Most of the helms in the game are non slotted. There are some lvl 15 worship helms out there from raffles and some lvl 1 one slotted helms from a forum event; both look like a normal loxe helm. There are also quite a few level 30 dread loxe helms from AP events. Legendary and Goddess helms are not in our version of the game yet nor is the lvl 58 Ophisoton, none of which are pictured. But there is a non legendary 5 slotted Sephiroth helm. Normal helms are from quests, usually involving turning in 30 cores of some type in exchange for the helm.

Loxe Helm - level 30. The plain version is from a level 29 quest in Arktus Ville. You need to collect 30 spirit cores to trade for the helm. Spirit cores can be found from the Sealakels just south of the town or the Goblin camp to the south east. The dread version of this helmet is a coveted item for PvPing in the 20-30 zone, it is only from AP events.

Wilarin Helm - level 37. The plain version is from a level 36 quest in Silvaren. You have to collect and trade 30 mare cores for it.

Sephiroth Helm - level 44. The plain version is from a level 43 quest in Stronghold. You have to collect and trade 30 pint cores for it. The Legendary helm pictured above is not in the game yet. HOWEVER there has recently been a promo for a 5 slotted version. It is NOT the Legendary version, which means a few things. All modes can wear it, it has 5 slots for lapis, it has no stats or MP,SP,HP bonus on it, and it looks like a normal Sephiroth helm.

Anor Helm - level 51. The plain version is from a level 50 quest in Apulune (the blacksmith outside of the city). You have to trade 3 level 3 endure lapis and 15 dark mages stones for it.
