Please help me identify these flowers

Because I have so less free ground space around my house and because the weather is so good, I grow flowers mostly in pots on my terrace( roof). I started planting in October last year and finally in March of this year, with the Spring rains, the seeds have started showing their flower power.

But I can’t identify some of the flowers that have grown in my pots.I am putting them up here, so my gardener friends can help me identify them.

Here they are :

Roof flowers -3

I want to know what these maroon and yellow flowers are.

Roof flowers- unknown

They have a pretty pink cousin too !

What are they ?
