#1- Maybe a pink flower form of Oleander (Nerium oleander). Check out the link below for more information, click on images to enlarge. Best wishes! #2- Looks like a bulb plant. I can’t clearly to tell, but with out its flowers, it will be difficult to guess even which genus this belongs too. Maybe you can give us an up date when it blooms. #3- Can you give the plant’s side view & a closeup of the leaves and main trunk? Top down view is hard to tell. But with flowers will help narrow down quickly. https://en.wikipedia.org/wiki/Nerium
