Sometimes the rules, the situation and luck conspire to make a lousy game session for one or more players--through no fault of their own. People play D&D to play D&D after all and sitting around for hours on end without being able to participate can be excruciating. I can't fault the player for being pissed. I've wasted enough hours out of the action in 3.5e games to feel their pain.
5e is a heck of a lot better than 3.5e or Pathfinder in that regard. Rounds move faster and most effects give you an automatic save chance/round or chances to break Concentration. Still, high-level effects are still potent, high-level play still seems to be balanced around neutering half the party to prevent them ganking the baddies in a single round, and the only good defense against spells is other spells. D&D doesn't transition gracefully from scrappy adventurers to potent demi-gods and high-level balancing is usually just foisted on the individual DMs.
I do think it's fair to use save-or-suck spells vs. players, but I certainly use them with care (which it sounds like the OP did, other than missing the banishment effect of prismatic spray). I certainly wouldn't ask or expect a player to sit around for hours and not participate in the game--I do whatever is necessary to get them back into the action in some form as soon as possible. I even let them advise and help strategize if they so choose since they are still a player in the group even if their PC isn't with the party. If there's no solution to get them back in the game, I'd happily let them leave with no hard feelings. I certainly don't want a someone to feel obliged to hang out if they're not contributing and have things to do.
As to the OP's dilemma, I take it from the situation that the afflicted characters were not protected by anti-magic allowing the spells. Which means that they chose to make themselves a target--to run the risk of being hit with high-level magic. Sure the overall effect was a bummer, but they acted heroically and drew high-level slots away from the baddies. That's something of an upside.
EDIT: Sounds like a fun game.
