If a weed killer was applied last year on mint and it came back this year, is it safe to eat?
After that length of time I would say, yes.
It is best to keep all chemicals away from your culinary herbs.
Use organic pest control and pulling weeds by hand is the safest way.

I have several mint plants that a friend dug up from along a chain link fence. They were in competition with grass and weeds for sun, so they are tall with bare stems and a few leaves on top. How can I get them to grow lower and bushier? Please use layman's terms, as I am not an experienced gardener. I tried to load a picture, but my camera isn't working. Can I just cut them low in the pot? Will they grow back?
It's a good thing your mint plant is in a pot, because it's almost impossible to kill and will spread like crazy if unchecked. Yes, you can absolutely cut it back and and it will continue growing. You can do your best to try to shape it the way you want, but mint grows pretty uncontrollably so you'll have to stay on top of it.

Where can I buy the Red Raripila Mint plant?
Do a Google search for this mint plant and many mail order sources can be located.
Check you local garden centers and even Ebay is a good source for plants.
Sorry, I don't know name of my mint in my garden. You can see my photo and tell me about it. Thank you so much :)
I'm sorry but it is difficult to identify the variety of Mint you are growing, many mint varieties look very similar. There are hundreds that look just like this image!

I have chocolate and peppermint, neither likes full sun - period. They begin to die. Secondly, I am able to root cuttings. I then plant in large pots but, again, growing in height not width. Why? I am wanting it to spread, as I have an area I wish to plant for ground cover.
Here are a few links.
I grow quite a few mints, and I agree many tend to grow up first, then you will start to see runners being sent out from the plant.
These will spread out horizontally.
Be very carefully because all mints are very invasive.

As seen in attached pic, some random mint leaves (even young leaves) will show white veins/spots. What is happening and what should I do? Please help me. Also, is my plant a peppermint plant?
It looks to be Leaf Miner on your Mint plant.
Neem Oil is a good treatment for this.
