The first two as well as the last two are Ipomea tricolor, the middle photos I'm unsure of but look very beautiful, the Ipomea should be developing seed pods and could be harvested over the next couple months, wait until the seed pods is a bit brown and crumbles easily and grab some seeds. Be sure to leave some for mother nature and years to come. These things spread like crazy and if you ever grow them you will have them all over your yard in a couple years.

Travel like a king
Listen to the inner voice
A higher wisdom is at work for you
Conquering the stumbling blocks come easier
When the conqueror is in tune with the infinite
Every ending is a new beginning
Life is an endless unfoldment
Change your mind, and you change your relation to time
Free your mind and the rest will follow
