PHOTO EDITING APPS FOR APPLE?

I'm looking for Apps where I can make my Photos look like the following.

Due to limited space due to buying my iPhone 6S at Walmart I only have 16 Gigabytes of Storage, therefore that results in me only having a total of 10.5 Gigabytes of Storage due to the pre-downloaded Apps.

If you know an App that lets you edit Photos like more than one of the below, or even two or three, just name that App, instead of individual Apps as long as it has what I'm looking for and is good quality and has a small capacity, so I don't take up my storage. I don't want any apps that I must pay for

I also need an App with over 100 Filters, and an App with over 100 Collages. I want something that has filters like the bottom right photo of the girl, the colorful one.
