Not really.

Shadows of Valentia and Metroid almost certainly made a profit, even as being somewhat high quality 3DS games. 

Ever Oasis and Hey Pikmin maybe. That's still 3/5 games. Even Miitopia sold modestly well this year. So more like 4/6

That's all I'd describe these games as. "Modestly well". But then again that's probably what Nintendo expected.

*Edit: That being said, this is one of the few cases where i'd *welcome* ports being marketed as big console sellers. It's honestly crazy to me none of these games had versions that shipped on Switch at the same time. Well ok .. it's not really crazy when you consider that would have taken money xD Still, that would boost at least Metroid quite a bit

Source or are you just assuming they're making great profit? I'm assuming they're not making much profit if any as the sales are just so low, even though yes most of these are budget games reusing assets n engines n such.

Switch install base is still small so Norway that's why people are not buying them. They all look like small budget titles by modern standards so I'm sure Nintendo made a healthy profit.

Pokemon will do much better then them all though. And Nintendo are right to do it. They can't supply enough switches so have to sell games to their other fans still on their last gen console.

I don't have sources, but with how cheap it is to make these games, I assume they wouldn't lose much anyway. After all, Nintendo is rather conservative when it comes to these things, and I'm sure they planned on supporting the 3ds for a reason.

Once it stops bringing money, then they'll cut it. When will that happen? I'm not a fortune teller, but by April of 2018 we'll probably see it be close to dead.

People are still buying the hardware (been trading the #3 spot with XB1 almost all year), so makes sense to support it with some new software even if it's not selling like Mario Kart 7 etc; Plus these titles have probably been in the works for years, why scrap them? What ever $$$ they spent during development is already gone, why not try and recoup at least some of it?

Yal have brought up some good points that after thinking about made me now disagree with my own OP. You're right that even if these games don't bring in much profit, it's still better than nothing, and even more importantly they give Nintendo goodwill that'll help them in the long run and gives them an excuse to keep promoting the 3DS which still has value as the cheap portable. Will edit title and OP.

If you look you will see that Nintendo 3DS games for this year are mostly ports/remasters, spin offs and small projects, so if those games have low sales thats not relly problem.

Ever Oasis and Hey Pikmin flopped pretty hard. Fire Emblem Echoes is already the third FE game on the system. Miitopia did quite alright I think. Metroid won't do bad either, thanks to the fair amount of hype it got, but of course Metroid isn't a big franchise sales-wise.

But yeah, they would all have sold more without the Switch. The new Metroid and Fire Emblem games looked pretty good to me, but I didn't buy them because I wanted to buy Switch games instead.

Surely Pokémon will reach a million?

This thread will cease to exist at the release of Pokemon. Wich was the only Nintendo game released that was aiming at the million. Fire Emblem Echoes could have sold one million but flopped in Japan where it was seens as a remake.

Anyway, the third party are selling much more on 3DS than on Switch, with Dragon Quest 3DS outselling the PS4 version, Monster Hunter XX selling above one million and much much more than the Switch version.
