Yes.

Given decentralized the nature of the application, it may not be
practical to license under AGPL, since it's intended to protect users
from the infrastructure owners.

In this case, plain GPL seems more appropriate.

Beware, GPLv3 and AGPLv3 are compatible through explicit mutual
compatibility clauses. GPLv2 is incompatible, so unless the code is
licensed as GPLv2+, it would be a violation.

Interactions with Apache License should pose no problem, but CPL
does. Neither CPL nor EPL are compatible with the GPL, so you must
replace that code or get it licensed under a compatible license.
