Any good anime that are like Grimgar ?

Like Grimgar? Honestly, none. There is no isekai where people die. In Goblin Slayer people die, but those aren't even side characters, just unknown background characters. Goblin Slayer isn't an isekai either.
Concerning characters that die, the one that comes closest is the first season of Attack on Titan.

Maybe give CHOYOYU! a try it has somewhat 'mature' writing for an isekai.

Personally, Grimgar was an average series beyond its colorful appearance and different character personalities

Simply looking over your completed list your really not going to find anything like "Grimgar" in my opinion that you haven't already completed already. The fact that you made specific criteria for what you are looking in an Anime extremely limits all options to almost an impossibility to find anything like "Grimgar" at all. I would strongly suggest expanding your Japanese Anime horizon and look towards Japanese Anime you wouldn't be normally looking foe even like "Gunslinger Girl" or even something like "Baccano!" (that is if you can get your hands on decent enough copies to actually have an enjoyable experience).

The thing I see is "Grimgar" is a pretty unique Anime in itself for either an Isekai or even fantasy Anime. I would even recommend "Claymore" if you could look past the Battle Shounen type pacing and mild undertones of DBZ effect trash talking during combat. Which would be the main reason I wouldn't normally recommend something like the 2022 "Bastard‼ Heavy Metal, Dark Fantasy" ONA unless someone really just loved the original 1992 "Bastard!!" OVA.

If you are simply looking for something more modern you haven't seen yet that is simply an excellent entertaining experience just like "Frieren". I would totally recommend at least checking out "The Apothecary Diaries"... and if you don't like it after watching a few episodes you can just simply drop it. When I 1st watched "The Apothecary Diaries" I had very little expectations for it, then found it to one the best seasonal Anime I have seen released in the last two years.

If I recommend something based off your 5 requirements then I'd say:

Akatsuki no Yona
Arslan Senki
Raven of the Inner Palace
Kemono no Souja Erin
Juuni Kokuki (the downside is dated animation as it's from 2002. It's fits all your other requirements though)
Shoukoku no Altair
Sacrificial Princess and the King of Beasts
Seirei no Moribito
Mo Dao Zu Shi (Chinese donghua but does have a Japanese dub in addition to Mandarin)
Tian Guan Ci Fu (Chinese donghua but has an English dub in addition to Mandarin)

I never would have thought I'd write this when I started watching the series, but Dungeon Meshi gives me a lot of Grimgar vibes since around the half-way point.

It checks your five points decently. However, at the same time it's still a gourmet comedy. It totally makes sense once you've seen episode 12.
