Yeah. Sambucus! It's actually S. peruvianus, whereas yours was S. nigrum (I think). Since we've IDd a bunch more and run to two pages, here's the key to date and the remaining hinted one.
No, and close. #5 is a monocot, but it's not related to Pandan. It is a food plant, though. Check your geographical distributions; the plant pictured in #5 was growing in the wild in a mixed dry forest at about 2200 meters of elevation. Quick taxonomy check tells me that #8 has been reassigned to the Kalanchoes, so I'll give that one to you. I know is as Bryophyllum pinnatum, and the rest of the world calls it Kalanchoe pinnatum. At any rate, the common name here is Chiriyugyu (all-heal plant in Kichua) or Wind Flowers.
