Erza, Mystogan, Gildarts, Mirajane and Laxus are S-class mages, as is presumably Makarov.
Gajeel joins Fairy Tail after the Paradise Tower arc, along with Juvia, who had been helping Natsu's team since the Phantom Lord arc finished.
Laxus is a '2nd generation' Lightning Dragon Slayer. Rather than being raised by a dragon, like Natsu, his father implanted a dragon magic lacrima crystal into him when he was a child, giving him dragon slayer powers.
'Like' is a bit of a stretch for Gajeel, the most I'd say is he feels an obligation towards her due to the time when he attacked the guild, severely injuring Levi, Jet and Droy.
As of right now there is several pointing to Levi and Gajeel getting shipped as a couple.
Cyperus laxus was created in 1791.
The 7 known, living Dragon Slayers are Natsu, Gajeel, Wendy, Laxus, Erik (aka 'Cobra' of Oracion Seis), Sting and Rogue. The wizard saint 'God Serena' was also a Dragon Slayer, 2nd generation like Laxus and Erik. Under his epithet of 'Hybrid Theory', he had the lacrima of multiple dragons inside him, giving him a wide range of attacks. His fight against Acnologia went poorly though, and he was slain in a split second. Acnologia himself was revealed to have been originally human, and was one of the first Dragon Slayers.
The known dragonslayers are, Natsu Dragneel, Gajeel Redfox, Wendy Marvell, Laxus Dreyar, Cobra, aka, Erik, Sting Eucliffe, Rogue Cheney. 'God' Serena. The black dragon, Acnologia, was once a human dragonslayer, but if that was his human name too, it has not been made clear.
Natsu - Fire, Lightning, Wendy - Wind, Gajeel - Iron, Shadow Laxus - Thunder, Cobra - Poison, Sting - Light, Shadow Rogue - Shadow. 'Future Rogue' - Shadow, Light Acnologia - unknown God Serena 'Hybrid Theory' - he has eight different powers.
Erza, Mystogan, Gildarts, Mirajane and Laxus are S-class mages, as is presumably Makarov.
freed, or laxus
From the Latin word laxus, meaning "loose"
Erza is considered the more powerful character in Fairy Tail. This is because the character has more mystical powers than Gajeel or other characters.
Gajeel is on fairy tail's side ever since he joined them. Gajeel is a very loyal type of character and can be easily seen when he used to be a member of the phantom lord guild and tried everything he can to obey his master's orders. He was shown to be spying on Fairy Tail for Raven Tail's guildmaster, Ivan. However this was a ruse, he was actually spying on Raven Tail's activities and reporting those to Master Makarov, while feeding fake information to Ivan. Ivan is poleaxed by this revelation during the Grand Magic Games, his hand-picked 'anti-Fairy Tail' team demolished in seconds by Laxus.

It's motion sickness, just like Natsu
