There are four achievements for scoring the Wonderful Hero rank. Ultimately, you'll need to get that rank on all 50 quests on Hard difficulty:

A True Champion Against Evil (25)
Have a rank of "Wonderful Hero" on 50 quests, on hard difficulty, in Hero 30 mode

There are two achievements for completing quests below their target times. Ultimately, you'll need to do this for all 50 quests, but only 25 of those need to be done on Hard difficulty - the rest you can finish off in Normal:

Half-Minute Hero (25)
On normal difficulty (or higher), clear all quests under the target time, in Hero 30 mode

Time Lord (25)
On hard difficulty, clear 25 quests under the target time, in Hero 30 mode

The Wonderful Hero rank is also granted based on completion time, but with a twist. From what I've read, the base time limit matches the target time, but you can increase that limit by 30 seconds for each title earned on that run. Sometimes you can clear both titles in one run; sometimes they're mutually exclusive. The time it takes to unlock a title may also be greater than that extra 30 seconds, so it may just be quicker to dash through to the Evil Lord ASAP.

On Hard mode, many target times will seem impossible, but grabbing titles during the quest will at least let you get Wonderful Hero on each one. Just make a note of which levels you could not complete under the target time on Hard, and take care of them on Normal instead.

Here are some details on each quest's target time, plus recommended titles to go for during a Wonderful Hero run. Target times I could get on Hard are bolded and italicized.

The strategies described in https://gamefaqs.gamespot.com/psp/956931-half-minute-hero/faqs/62779 are pretty spot-on. You might need to experiment with different equipment sets, but it will mostly come down to timing and execution.

I've brought together several online sources for completion of the Goddess Room, including info at www.role-playing-game.net (retrieved via archive.org's Wayback Machine and translated from Japanese) and the Half-Minute Hero wiki (https://halfminutehero.fandom.com).

Bullwood Hell	Hero 300 (lower-right magic circle before final battle - accessible if your average Knight 30 rank is "★Great Knight")

The Hell monsters are more difficult than the final boss of Hero 300. You'll need to grind to level 50-55, then dash into the enemy for at least 30 seconds to win. Start with Dragon Hell (it seemed easiest) and finish with Bullwood Hell (it seemed to be strongest, even with the extra levels from defeating the other three Hell monsters).

Slayer of Evil (25)
Complete the Evil Lord collection in the Goddess Room

This section of the Goddess Room lists all of the Evil Lords defeated during the Hero 30 mode. You will necessarily fill this out as you complete other achievements. The one you might miss for a while is the Evil Lord in Quest 25: Another Goddess - that quest can't be properly completed until you defeat 108 Evil Lords on that same game file. Work on filling out other Goddess Room lists and attaining target times / Wonderful Hero ranks and this quest will open up eventually.

The Envy of All (50)
Complete the art collection in the Goddess Room

This will also naturally fill out as you finish other achievements. Once you fill out the Item, Monster, and Evil Lord lists, visit the Goddess Room from the main menu - the final artwork should unlock to signify 100% completion.
