How to edit pictures like popular Instagram users?

So I want to start taking pictures again & putting them on Instagram. Something I've always struggled with is the editing. I want my photos to look like the links below, with a vintage grunge film look. I have Lightroom 5, and Photoshop 6.0 (not CS6 6.0 the ancient one)

In addition to PS and LR, I have some random little iPhone editing apps that have filters and stuff. So can someone please tell me what you do in these apps to achieve the vintage film look in your photos? Thanks!

Trial and effor. You'll establish your own style that way. Learning on your own. Read a few books on basic edits. @geniusphotoraphy <-Instagram

IPhone has a lot of great apps! I use vscocam and afterlight the most. They give out a slight vintage look. If you have photoshop, you can do lots with that too! Try searching on google how to edit photos vintage on Photoshop. But vscocam does the trick for me and I love it! Here's one picture from my IG that I used vscocam.
