Hi. My take on your list:

Elementh: strong team (but mostly from the one country, which is Russia), a good looking idea and an existing MVP. Advisory board looks random, but still well connected. But the market is competitive, and their legal setup and token emission targets both do not look good to me.
I would be careful with this token, it will drop right after the ICO (too many bonuses and free token given away; )

Bulltoken: A very strong and experienced team, rather diverse. Headquarters ans key managers in Norway (which is great for the safety). Impressive advisory board. Looks like they do not use cheap bot marketing, almost no dead accounts on they social media followers. Very solid project.
I personally invested in that one. And this is my favourite from your list.

Betrum - I didn't even find that one. Can you give a link (sorry, if I missed it, but couldn't really find it)?

Ziggurat ICO looks very weak. It is just poorly ran ICO, no good web site, weak WhitePaper. Idea is OK, though. But if the execution will be as it is during their ICO, then it has no chance to survive.

Can't tell much about others, didn't really dig into them.
