1st name is a two tank fight like you said. one charms, one ports.
2nd name can be one-tanked if needed like you said, make sure people with curses joust out 30m at least, or you throw up blockers right before they expire.
3rd name is a pain in the ass for the loot it drops. just burn through everything making sure blockers are up as much as possible. couldn't kill it with under 500k since adds memwipe and become way too much of a pain to handle. Also has a curse(main reason for the blockers) that seemed to go out when the mob was around 80%, 50% and 30%, maybe it was just time based or something though. The curse reduces cast speed and reuse by 150% and basically sucks since you're whole group gets it and unless you're running with 6 healers...

to top it off the name memwipes along with the adds.
4th name is cake, burn the mob and if anyone dies make sure to kill the fungus that spawns asap. at around 20% block it as it will do some kind of ae that seemed to one-shot squishies, causing multiple fungus to spawn and wipe from their aes. this mob memwipes as well.
5th name is extremely difficult to kill. i know of people in HM gear with two groups that can't beat that encounter. But basically the strat is, burn the two adds that come with the name, then when two more adds pop (envy and greed) burn those and try to have blockers up as they were ae'ing toons for as high as 60k crushing. the two miniadds come every 45 seconds or so. basically after ~40 wipes on that mob its not worth the effort for the plat from selling the items lol.
6th name i've seen videos of and seems easier than the 5th name, but can't get to it until the 5th name is dead
