Lucy could easily solo Ajeel in a serious fight. She outclasses him in smarts, physical strength and types of magic. Also maybe speed.

Scorpio star dress: Lucy simply negates his sand using her sand magic.

Virgo Star dress: Lucy could easily move through Ajeel sand with incredible speed. Even if he hardens his sand Lucy will still go through it with incredible speed.

Aquarius mode: Lucy uses this to combat Ajeel dehydration spell.

Taurus Star dress: She would easily best Ajeel on physical strength.

If she combines all these star dress then I don't see Ajeel logically defeating her. So I am pretty sure Lucy can take down a 12 Spriggan member.
