please id these plants

took pics of some leaves while having my morning exercise. please help me id these plants.

 

4 looks like Alternanthera, Party Time Plant.
2 Aphelandra? Thought maybe Fittonia, but I am voting Zebra Plant.
1 I should know but maddeningly can't think of.
3 no idea.

 

I'm pretty sure 1 is Acalypha, but I see so many similar to that on google, I'd never guess which one.
3 looks like Breynia.

 

1 is one of the many cultivars of Acalypha wilkesiana
2 is Sanchezia nobilis
3 is a dwarf variegated form of Pithecellobium dulce
4 is possibly a Pseuderanthemum, perhaps one of the cultivars of P. carruthersii

 

for clearer view of number 3

 

another picture of number 3.

 

Pithecellobium dulce i am not surei am familiar with this plant and it is thorny and we eat the fruit. . i uploaded another picture of the shrub which is commonly used in landscaping here.
