Q: Will this work with a MagSafe case on the iPhone or will the case need to be removed each time?

It should work fine, I have a Apple leather case on my I-phone and my wife has a clear rubber case on her I-phone, both charge perfectly on this charging station. We also each charge earbuds and Apple watches all at the same time. Good luck

Q: Does this work with samsung watches?

Yes. If the watch can rest on the stand, it will charge.

Q: Does this work with se watch and iphone se 2?

I'm sorry I have an android so I don't know about iPhone sorry

Q: Do I need to insert my own apple watch charger into the stand？

You do not! You just plug this stand in (one plug) and you can charge you phone, watch, and airpods. One of the best purchases I have ever made. Very fast charger and has worked like a charm since I plugged it in. LOVE it!
