Thoughts on these coins ?

I'm back with another question please. I'm going through storage and found these old coins. Long story short, in the early 2000's I went to Bulgaria (stopped at the Heathrow Airport in London) and went to the Dominican Republic. These coins are from those trips. I tried to label them below in the order they are seen in the photo from left to right. If anyone has any thoughts on what these may or may not be worth it would greatly appreciated. I have no experience with this at all. Thank you !
