Thor brings the armor he used to stalemate thanos.
Superman gets the belt of strength. Surfer ports him to a blue sun which powers huim up faster than a yellow sun. On top of that surfer should be able to direct more energy into supes than if supes just sits in the sun (think how WS atom overloaded apollo, except you cant overload supes).
They breeze past hank and supes gets another hour of sundip.
Thor stalemated thanos in the mpire (or maybe beat, cant remember). Blue sun supercharged supes makes them destroy him.
Bit of simple stratting. Surfer or thor ports him into a red sun than Ko him easily.
They can rupture the suit and thor should be able to absorb all the nergy into mjolnir.
Depowered tyrant was beating thanos but not bya massive margin. They should take him with their equipment & sundip.
H/P doomsday is hard to qunaitfy so i'll leave him but im inclined to say they can win.
Even though the list is out of order, they stop at Monarch. Prime might kill them, but SS can easily Amp Superman can de-power(won't be much) Prime. Considering Prime hates Superman, he will just attack him, not paying much attention to SS or Thor. Monarch on the other hand wont take that crap. He KOs Superman and Thor in one hit and proceeds to KO SS with a blast.
That otally ignores them having one sided prep though.
SUrfer doenst need to depower prime when he can port him into a red sun (which supes can make him aware of in prep).
A blue sun supercharged superman witha belt of strength should be strong enough to rupture monarchs suit IMO
They clear the first 3 without too much trouble then beat Prime after a good long fight. They're not clearing 4 or 5 so order doesn't matter much even though Monarch should be above Tyrant.

First of all, there is no BFR, if there is, it's stupid. Thanos can Teleport, Prime can get out of almost any BFR, and Monarch can BFR others and teleport himself; Tyrant as well.
Second of all, Monarch KO's characters like Superman(even stronger) with easy back hands. Giving Superman extra power won't change the fact that his durability wont change. Monarch also tanked hits from many Superman, Captain Atoms, GL, WW's and others with no sign of damage.
However, like Philo said, If Superman takes a Sundip(for one hour), it's probably a spite. a few seconds worth of sun dipping gave him enough power to easily kill characters he couldn't before (DS, Imperiex).
Its not BFR if the team reloacte iwth him is it? If surfer and thor both travel to the red sun with him theren ot remving him from the battle, there just moving the battle.
SUndipping does increase superman's durability significantly. Blue sun's supercharge them faster and beings like surfer have shown to be able to transfer solar energy mmore quickly to those who can absob it (WS atom & apollo). The belt of strength will also double supes' durability.
And thor is asgardian armor was thanos' physical equal.
