What level of skill should I have before applying for jobs as a Junior Developer?
What kind of programs should I be making?

It depends on your location and market needs. Although i was capable of creating web apps and websites in PHP, i couldnt find a job in a 1,5 year period, asking for a junior position. A friend recomended me to a company and they gave me a UX manager position. Sometimes job hunting doesnt make sense. Apply to every job position you find interesting and ask them the requirements. Start a side freelance as a website dev for extra income.

Fake it until you make it bro ;)

I applied to a Junior Front End position with only back-end experience. I got the job and am learning as I go.
