Tanya's squad was basically a wandering army, they can be somewhere far away (like in Quartet) and still wouldn't affect their world that much. Plus they haven't referenced any major events from their world, so it can be placed anywhere in the continuity.

As for the Re:Zero part, even before Petelgeuse's death, the continuity was tightly packed (allowing no place for Quartet to occur). As you will see in the anime, Subaru will experience his traumatic "resets" one after the other without a break. And with each "reset", he becomes more and more deranged (that's what I meant by unstable). He doesn't return to his regular kind mindset until later. What I'm trying to say is: Subaru shouldn't have his original personality while Petelgeuse is alive (as they were shown in Quartet).

His love is one-sided, but Emilia is starting to warm up to him. So who knows? It might even become mutual. Like I said, I do not have the data of Saga of Tanya the Evil. In Isekai Quartet's first epsidoe overall, Tanya did recall what she had been through in the original series before ending up in the new world. Later in Isekai Quartet's Episode 03, 04, 09, and 12 of Season 1 plus Season 2 04, the character of the original series Being X had been mentioned by Tanya. In addition, she had mistaken Ainz and Aqua for Being X.

In regards to Re:Zero, some of the past events had impacted Isekai Quartet: First, Reinhard saved Subaru from a trio of street thugs. Second, Subaru tried to buy Emilia's stolen insignia from Felt whom he saved from an assassin. Third, Roswaal hired Subaru to work as a butler in the Roswaal manor. Fourth, after saving Rem physically and emotionally during the demon beast incident, she fell in love with Subaru. Fifth, the royal selection. I am still researching the original series as we speak. Regardless of which series, nobody knows if Subaru's love towards Emilia would become mutual.

In regards to The Rising of the Shield Hero, the emotional and psychological scar that Malty Melromarc left on Naofumi disabled his sociability. After he and his slave companions ended up in the new world in Isekai Quartet, they adapted to the school while he realized he could never use slave crests. Thus, it became a challenge for him to open up especially to the students of Class 2. If Naofumi did not have the scar, he would have befriended Kazuma Sato and Subaru Natsuki over one thing those three had in common.
