None of the above are a valid IPv6 prefix. Please try, e.g.,

acl test {
fec0:ac10:40a5:1:: / 64;
};

p.s. the IETF has deprecated the site-local prefix, fec0::/10, (see
RFC3879). Although this does not necessarily mean applications do or
will reject the prefix, I'd basically recommend you to use global
prefixes, even for testing purposes.
