Looks like an Echeveria

Ohhh I see Malaysia is a bit different from me When #4 was in flowering for me Sun time here at longest is about 15.75 hours buds where easy to see and nearly ready to open and did so with lesser sun light time and finished flowering 12 days later. Temps where in the 80 - 92 F range at the same sun times mentioned and the time of day mine opened was 16:00 hours to 23:00 hours For now I can say your heaviest rain season might be a bit much for #4 although the soil you have it in does look nice enough to drain fast enough. Again odd #4 Messeb like water more than most succulents but doesn't like wet roots for to long of time in days the top will rot out on you if to wet to long. Your other plants would certainly benefit with a lot less water than #4 can handle Other than a season rain over watering concern I have think you'll do very well with yours. As caution I think it would be best if you could provide a tarp or tent for some over head covering during your heavy tropical rain season over the entire garden bed. I and others here appreciate you and want to see your plants in there best of flowering later too. In all honesty it's best to tell you to talk to some of your local people with the same succulent garden passion as yours and ask them what they do.

Majesty palms are probably one of the worst palms for keeping indoors, and yet you see them offered by the hundreds every year. When the danger of frosts are over, your best option would be to keep it outdoors as a patio plant. One more thing, they are heavy feeders. Make sure to give it plenty of fertilizer and plenty of water (at least that's my experience growing it in the ground). In the wild, they grow along river banks, and often times, their trunks are submerged in water (hence the name Ravenea Rivularis). I'm sure pot culture is different, which is why topher suggests to give it good drainage.

Agree with socks...just leave the mother leaf there until it dries up, shrivels and it will detach itself from the new plant. In the meantime, it is supplying moisture and nutrients to the young plant.
