Yeah, the big one is a She-Ra horse for sure.
Your pink horse with silver hooves looks like Valentine. And the other one is Mikado. (Check my website, link is in my sig.)
They look to be in decent shape, so I am going to base my prices on what I can currently see.
Valentine looks nice, hair in good shape overall. Not many accessories. Still I think she would be worth a few dollars if she has no major issues. Maybe around $4-$5
Mikado also looks nice overall. I do see some rubs to the hooves, but I don't see anything too major. Having her saddle, hat, and hair beads is a big plus! She is fairly common, but it is hard to find them in good shape. I'll say about $12 more or less, depending on the buyer.
Congrats on finding them! Ebay has some, but the sellers must think they are made of gold with some of the prices I have seen lately.
I hope I have helped you!
