The 360cameras is interesting as while the others are more possible future trends, there is an interest in taking 360 panoramic photos. I'm personally in with a lot of .co's .. more in the single word or single term .. but I've seen much worse than the ones you have. Only issue with .co is pricing .. while they certainly do sell, pricing can vary more than other extensions. If I were you I'd set these in mid-range $xxx and see what happens.
The main positive and negative with .co's is the renewals .. the higher (~$20) price does make them much more professional .. but they also make they more expensive to hold .. as such prospecting future trends can be a little pricey and thus more risky than in other TLD's.
I'm still scratching my head on these .. really on the line .. you might also want to sell them on a place like Flippa where you can actually write text and sales copy to hype them up .. that could make a bit of a difference.
Good luck with them!
