List of Timeline Guardians so far:
--Floralis--
-Esther (Third weakest, and only for one reason: Fragment can pass their Soul Armor to other people if they focus on it, and they would pass it to her if she needed it. She can consistently stall until help arrives or Malis leaves, but she often gets injured in the process.)
-Asami (Second weakest, though only beaten by Esther because of Fragment's presence. Could consistently stall Malis out, but if she was attacked when she doesn't have any Pokémon on hand she'd get injured in the process.)
-???
--Rainzen--
-Shine (The weakest timeline guardian, as he's only 11 years old and doesn't have much to defend himself with beyond a sword and some magic. He'd survive but it would leave him exhausted and injured, and he'd only survive by stalling until Malis leaves.)
-???
-???
--Malvine--
-Keldin (Sixth weakest. Would stall Malis out with no injuries sustained, but would be easy to track down as he stays near the ocean most of the time.)
-Miyara (Second strongest. Like Synthia, if Malis confirmed her status as a guardian he'd probably leave her be to avoid getting his butt kicked. Miyara is an Evolved Spectrobe who knows some tricks to end battles faster.)
-???
--Veanlin--
-Lya (Fifth weakest, but second most elusive. He keeps his status hidden at all costs, but if he were to be discovered, he'd still be tough to track down. If he did get attacked, he'd stall Malis out with minimal injury.)
-???
-???
--Antel--
--Alghan--
--Taelon--
-Niro (Sixth strongest. His scythe skills might not be super close to Malis' scythe skills, but they're still something to watch out for. He could force Malis to retreat, but would get injured in the battle.)
-???
-???
--Aquaria--
-Alan (Third strongest, at least after regaining his old powers (which happens a little later in lore). He's a pretty powerful mage with control over multiple elements, and while Malis wouldn't skip him like Miyara and Synthia, he'd only target Alan as a last resort because he's a pretty big threat.)
-???
-???
--Relentia---
-Maurice (Fifth strongest, and third most elusive. His experience as a rogue would make him hard to track down, and that same experience would let him defend himself at the cost of getting a little injured.)
-???
-???
--Ethazion--
-Iris (Right in the middle. Her sword's properties would let her at least defend herself, but her performance also wouldn't be anything to write home about.)
-???
-???
--Abronia--
--Selean--
--Syde--
-Chroma (Fourth weakest. As a sage in his world he knows how to defend himself, and he has his team of monsters to aid him in battle. He'd consistently stall Malis out without getting injured unless he was attacked with no access to his team.)
-???
-???
--Eseph--
--Ardenna--
-Synthia (The most powerful timeline guardian, without competition from the others. She has three legendary Pokémon and one mythical Pokémon who happens to have close ties with Dialga (that being Celebi), can escape to the Distortion World because one of those legendaries is Giratina, and she possibly has some powers of her own in case she for whatever reason has none of her Pokémon on hand when she gets attacked. Even if Malis confirmed her status as a guardian, he'd most likely leave her alone, for if he did attack, she'd kick his butt. She's also the most elusive, though Lya provides good competition there.)
-???
-???
--Evarisse--
-Via (Fourth strongest, and one of the only ones that personally knows Dialga. She could defend herself pretty well, but might get injured if she isn't careful. Worst-case scenario she can escape to Evarisse at any time with her Escape Orb.)
