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.

The first one is a Silver Spotted Skipper. Nice catch, you don't normally see them with the wings open. The second one is indeed a Hackberry Emperor.

I agree with Alexa on the first and I'm thinking the second is 'Honeybells'?

I wish I had Easy Going, it looks like a beauty, but my yellow has no peach, amber or pink veining or undertones. It's egg-yolk yellow and simply pales to lemon-cream with age. My main regret is that it blows too quickly to a very open, unattractive form. This describes my 'Easy Going'. Actually "the light green shiny foliage" comment makes me lean towards EG, also the growth habit of your standard. Livin Easy, Easy Going, and the offspring Hot Cocoa have very distinctive foliage, prickles, canes, and growth habit. What makes ID trickier in your case that you are in Europe, where there are cultivars we don't have here. Easy Going and Livin Easy are very popular as standards here--whether or not that is true in France, I have no idea. Usually though standard roses, which are much more expensive than the regular ones, are less apt to be an obscure variety because of the extra expense. So look at very common cultivars. Have you looked at Sunsprite and Sunflare? Might also be one of those. Easy Going foliage:
