You don't know what you are getting into son. Given the discussion you have sparked so far, you can tell the lads have been waiting for somebody, anybody, to start a thread like this.
I think Erza, Laxus and Jellal deserves a much higher score for their magic power than what you gave to them. From the beginning of the story, Jellal created and maintained a thought projection in Siegrain, who has enough magic power to fool the Magic Council into giving it the title of one of the ten Wizard Saints. During the ToH arc, Jellal regarded Erza as having the magic power to qualify as a Wizard Saint too.
Laxus has always been consistently portrayed to have higher magic power than Erza. He was completely unaffected from Mystogan's sleep spell. Apart from Makarov who could partially withstand it but still drowsy from the effects, it knocked out the rest of the entire guild, including Erza and Mirajane.
Before the Battle of FT began, Laxus surrounded the entire Magnolia Town with Thunder Palace, filling several hundreds of lightning lacrima orbs with his own magic power that threatened to eradicate the city when released at once. It took Erza at her maximum effort to take down 200 of these lacrimas.
He proceeded to clash with Mystogan, creating a shockwave that blows out the windows of the Kardia Cathedral.
Laxus then fought Erza, Natsu and Gajeel. During the midst of those fights, he expended a ton of magic power on casting Fairy Law, and he was still whooping Natsu's ass towards the end until the latter received a second wind of power of feelings after Gajeel's sacrifice.
Laxus could negate Mystogan's Skycraper illusion spell through sheer magic power. Erza was susceptible to Midnight's Nightmare, and had to rely on her artificial eye to overcome the spell.
If I were to estimate their magic power during the ToH/BoFT arc, they'd probably be somewhere around
Erza: 5000
Laxus/Jellal: 7000
Erza was amazed by Laxus' strength when they were fighting Hades.
Tenrou Island (x784)
Erza (vs Azuma): 6000
Jellal (imprisoned): 7000
Laxus (vs Hades): 8000
Makarov: 8500
Hades: 9000
During the GMG (post first timeskip), Jura scored 8544 on the MPF. While Cana wielding Fairy Glitter obtained a score which exceeded 9999 and broke the MPF. Which isn't that surprising as the spell belongs to branch of magic that includes Fairy Sphere, a spell that has proven to be effective against Acnologia twice. Laxus narrowly defeated Jura in their fight, while Jellal seemingly had Jura on the brink of defeat before their fight got interrupted by Ultear.
GMG (x791)
Erza (in stasis for 7 years, unlocked Second Origin and grew stronger during GMG): 8000
Jura: 8544
Laxus (in stasis for 7 years, grew stronger during GMG): 9000
Cana (with Fairy Glitter): >9999
Jellal (Ultear and Meredy broke him out of prison in x785, likely unlocked Second Origin too): 10,000
Erza could dispel Neinhart's Historia of the Dead through sheer magic power and her resolve. Laxus destroyed Ajeel's tidal wave and was about to kill him with a casual attack, killed Wall despite being severely afflicted. Gray and Natsu were shocked at Brandish's magic power, placing it higher than Makarov's. Invel outclassed Gray, but shit his pants at Gray's magic power when the latter revived. Gray pounded Invel's face in, then clashed evenly with Natsu. His Devil Slayer magic advantage should cancel out his ice's weakness to fire. Gray still had enough in his tank to almost succeeded in freezing Zeref with Lost Iced Shell. Brandish's mass manipulation magic could work on Gray.
Alvarez arc (x792)
Gray (before fighting Invel): 10,000
Natsu (before his anti-ethernano tumour healed): 10,000
Ajeel/Invel: 12,000
Neinhart/Wall: 13,000
Gray (after defeating Invel): 14,000
Natsu (after his tumour healed): 14,000
Brandish/Erza: 15,000
Laxus/Jellal: 16,000
