I need some recommendation for long H-manga (More then 5 chapters) that not Loli or insect

I believe you actually mean incest? Though it could actually be insect as well, since I do know a few that feature insects

And overall, over 5 chapters is kinda easy since most single volumes feature more than 5 chapters.

Kyoushi to Seito to as well as some other tanks of the same artist. At least two of them include incest though.

Yanagida-kun to Mizuno-san is a solid two volume set.

Makunouchi Deluxe is 3 volumes and Rin x Mama from the same artist has 5 volumes.

Older, dead funny single volume Slut Girl

Right then. All of these fit the stated conditions of
1) Continuous story featuring same set of characters
2) 6+ Chapters
3) No loli or incest

Mamagoto

Boing Boing Teacher + sequel Boing Boing Onsen

Those beneath have some slipping on some of those, I'll mention how for each separately

Safety Lodging House Utopian has a loli during one chapter plus co-starring a few pages later on.
Ane Haha Incest with aunt, her daughter
Brandish One side character is loli-ish.
HHH - Main story only. The last oneshot is about incest.
Anata o Suttemo Ii Desu ka? One loli character, far older than appears
Princess Propose One loli character.
Please Help Yourself, Master! Chapter 9 has few pages of incest.
Witchcraft One loli character, far older than appears

And some borderline H you should read anyway, if you haven't already

Velvet Kiss
Koi wo Suru no ga Shigoto desu

Yeah, that should keep you busy for a while.

I can recommend Pisu Hame!. Excellent art and engaging story (yes, really!). Consists of 16 chapters if I remember correctly.
