Yeah, my thinking exactly. Reverse image search turns up only one of the pics, the one with the shirt pulled up half way, which is all over the internet, but all of them pins on pinterest I can't manage to use to find a source.
"Kindly send messeger for appointment direct to my cell phone faster respond, No CALL or No E-MAIL please,just text Messenger only for faster respond."
Gets kind of expensive to send a messenger to set up a massage appointment. ;-)

Pics belong to a Brazilian model who came onto the scene ~2012, which is consistent with the escort speaking Spanish and Portuguese, but I'd be careful about whether the pics are current. The masseurfinder pic suggests that aren't quite.
AidenBig seems to be new, but be careful. The phone number has been used for a bunch of women escorts in Miami and Houston. He has advertised before under the names LiamBig and LiamX. Several of the pics are all over the internet. Lots of red flags.
As for SergieS: https://www.companyofmen.org/threads/dc-411.128921/#post-1371256 (and see the links in the thread).
Search for Fabiobrazil and you'll find plenty on him.
This guy is almost certainly a fake: https://rentmen.eu/UNCUTnextDOORXXL
Several of the pics are easily found on the internet, and the fifth pic is from Coolguy, who's also on rentmen.
This guy might or might not be, but many of the pics are all from 2010 and easily found. They are of a model with a highly similar name: https://rentmen.eu/Hugohot

Pics are definitely Diego Lauzen. His twitter feed doesn't indicate he's in NYC, but he's not tweeted since late March. Was an expired ad for him: https://rentmen.eu/DiegobrPornstarX
There are considerable differences between the two ads.
Has been a fake ad for him in NYC before:
