Well, 'Sword Art Online' has some elements that might be comparable. While it's mainly about being trapped in a virtual world, there are aspects of dealing with unknown threats, much like in 'Invaders from Another World'. There's also 'No Game No Life' where the protagonists are summoned to another world and have to use their wits to survive, similar to the concept in the mentioned light novel.
Sure. 'Overlord' is a great one. It also involves characters from another world and has a lot of interesting power plays and world - building. Another similar one could be 'Log Horizon', which focuses on players trapped in a game - like other world with its own rules and politics.
I think 'Re:Zero − Starting Life in Another World' could be considered similar in a way. The main character is in an unfamiliar world and has to face various challenges, just like in 'Invaders from Another World'. Also, 'Grimgar of Fantasy and Ash' has a group of characters in a new world trying to figure things out and survive, which is somewhat related to the theme of the given light novel.
