I think the first is correct, can't say for sure with the second but it looks close. There's a lot of species which are not well represented.
Elaphoglossum potosianum is similar to the original one posted! I thought it could be in Polypodiopsida, so found it on EOL, it could be a lead..

Microsorium dilatatum is similar but it's in Asia.. you might find there's two types of spore.

So many can be similar in looks but belong to a different genus or family though. More searching usually brings up more results.
