Which of these projects should I list on my resume? I have space for 3-4, but have a total of 5.

1) A "machine learning" project. I made a python package that takes in security camera footage and tracks the number of people leaving and entering and generates a CSV of how many people in the store at times and generates graphs too of how time affects number of people in the store automatically.

2) A qr code based cashless donation app for the homeless and for charities. This is in its very early stages and so only has a baseline made in Ionic Cordova, but I'm currently talking to homeless shelters and restaurants for partnerships before I develop it further. This makes me think I shouldn't have it on?

3) A mobile app made to help travellers get Google maps directions and translations without the need for data, only through wifi. This is pretty much done, I just haven't published it on the stores yet. I have screenshots on my GitHub though.

4) a website I made for my university where my classmates and I can upload solutions to various textbook/past midterm problems so everyone has answers as well for all of our courses. This was made with a friend.

5) a website I made that allows users of the steam (gaming) platform to compare what games they have in common with their friends.

Which of these should I list on my resume for general software development internships as a first year, in terms of impressiveness?
