Waves and ETH are good coins to hold for long time because these coins are used as smart platform for new projects using their service to build their platform. By the time being, ETH and Waves will be known as popular projects.

I think for a good long-term investment is the coin ethereum and bitcoin, but be careful to keep the coins in order not to lose

for the long term I still believe in bitcoin, but etherum, dashcoin, and waves also have good potential for the next 2 years, if you have enough capital invest on some coins so don't focus on one coin. I think 2 or 3 coins is enough to invest long term.

From your list I would only suggest waves for long term, but that too is risky. I'm sure you already know that BTC and ETH are probably the best bet right now for long term holding with the lowest risk factor. Go with them if you don't want unnecessary risk.
