If you look at diving with a buddy as a skill, then it is easy to see that diving with a buddy group of 3 is more difficult than diving with a buddy group of 2. If one does not see it this way, then one is not using the buddy system properly. If all 3 people have excellent buddy skills, a group of 3 is ok. Otherwise, it is a bad idea.
Not necessarily. I often dive 3-person buddy teams with my students. They don't have excellent buddy skills ... yet. What qualifies them to dive this manner is a willingness to learn those buddy skills.
Being a good dive buddy is more about attitude than skill ... skills can be acquired through practice.
A three-person buddy team takes no more effort than a two-person buddy team ... it just takes a bit more awareness of what's going on around you, and a bit of knowledge about how to "swim to be seen" ...

You missed your safety stop coming from 100 ft.. Its not an emergency so there is no excuse to miss it
You or your buddy gone missing after the time the gas reserve is exhausted before that time you are on a dive
and just got separated.
It's situation-dependent, as usual ... but if you and your buddy are separated, then it may well be or become an emergency. If there's current, or if conditions are bad on the surface, then skipping the safety stop may well be preferable ... especially if you're interested in maximizing your chances of reuniting on the surface.
As long as you're within NDL's, a safety stop is optional. What matters more is controlling your ascent rate, and remembering to breathe as you ascend. That latter may seem like common sense, but in the real world, a buddy separation causes some people a lot of stress ... and stress tends to make people fall back on instinctive behavior, which can hurt you bad underwater.
The other thing to keep in mind is that when you've lost your buddy, you're diving alone. If you're not prepared to be self-sufficient, then doing a safety stop may become more risky than not doing one. You always have to weigh the circumstances of the dive and consider the risks. Skipping a safety stop ... even on a 100-foot ascent ... presents little real risk if you've managed your ascent rate properly. Depending on your gas reserves, diving conditions, and your state of mind at the time, stopping to take one might create more risk than it resolves ...
