Well, I've got nothing on Zesshi but I do have the part about the DDDL. It wasn't a tweet but rather a pamphlet apparently handed out during a/the screening of an Overlord movie; don't know if it was the first or the second compilation movie. Anyway, I got it from here: reddit.com/r/overlord/comments/5wss1t/new_info_about_dragon_lords_from_the_author

To save the time from checking out the link, the translation was:

The Seven Colored Dragon Lord. A perverted dragon who the (True) Dragon Lords fear the most amongst their brethren. To describe how much of a pervert he's seen as, imagine seeing someone having sex with a goat while yelling "Get pregnant!". He has his own way of thinking, but is a loner because the others don't understand him. His residence is held at the top of a mountain located around the center of the continent. Intelligent like a scholar. Finds combat annoying.

The Dragon Lord of the Holy Heavens. He's huge! Looks more like some adventure-laden place than a living being. As big as the Rune nest's True Dragon? Feels like you'd hear someone comment "Hey, there's a Dragon Island flying there!" and "Yeah, there is. Most importantly, the weather sure is nice today" and never hear about it again.

The Deep Darkness Dragon Lord, who annihilated the players 300 years ago. Possess the ?????, one of the 20 world-class items, in his possession. His unique magic is damn strong and both his offense and defense is flawless, but unfortunately Shalltear is his nemesis. Against any other Floor Guardian, he would likely be victorious... Don't fight one-on-one? Deploy the Gargantua? Don't say that...>

Adding my opinion, I think the matter of the DDDL being "likely victorious" against NPC Floor Guardians other than Shalltear is akin to Shalltear having "7 to 3 odds of victory" against Ainz. The ratio may not be the same, but the advantage in odds may be in favor of DDDL. Well, that's just what I think.

the zesshi being stronger than lupusregina thing was never sated i think

Hmm... about that "Zesshi being stronger than Lupusregina", perhaps you mean that brief mention by Shalltear about the Captain of BS being stronger than Solution Epsilon in Vol. 3 Ch. 2 Pt. 4? If not, then I've no idea otherwise.

i think she talking about the trivia section on zesshi's page that had

"maruyama once tweeted that zesshi zetsumei is stronger than lupusregina beta"

but its not there anymore so im assuming it got erased cus its a lie

Maruyama's tweet about Zesshi being stronger than Lupusregina is true. His tweet was on November 11, 2015 when he was answering a fan's question.

Fan's question: "hello master, am your fan, you can answer me one thing, please? Who is stronger, lupusregina OR Zesshi Zetsumei?"

Maruyama's answer: "Zesshi Zetsumei is stronger."

ah okay

Ask date when maruyama-sensei said Zesshi is overlord new world please?
