Wales Online's January list of First Teamers whose contracts expire this summer was:

Callum Robinson, Callum O'Dowda, Dimitrios Goutas, Anwar El Ghazi, Yakou Miete, Isaak Davies, Kion Etete, Joe Ralls, Aaron Ramsey, Jamilu Collins, Andy Rinomhota and Jak Alnwick.

Since then Robinson, O'Dowda, Etete, Davies and Alnwick have signed new or extended contracts. So your list is right.

Not sure how many of the ex u21s on loan are at the end of their contracts.
