Fifa's Independent Appeals Committee, chaired by Bermuda Football Association president Larry Mussenden, will hear their cases.
Temarii claimed on 13 January to have received a letter from Fifa on 30 December in which he was "cleared [of] all corruption allegations".
He added: "The ethics committee have accused me of breaching Fifa confidentiality and loyalty, with which I totally disagree.
"I hope a meeting, possibly next month, will see Fifa's appeals committee realise I have not breached any articles within the code of ethics, nor did have the intention to."
Adamu hopes to be exonerated within weeks, clearing him to stand for re-election.
The Confederation for African Football (Caf) has its annual assembly on 23 February in Khartoum, Sudan, where it will choose two of its four delegates to the 24-member Fifa ruling body. Adamu is listed as a candidate pending his appeal.
Fifa says three more officials - former executive members Slim Aloulou, Amadou Diakite and Ahongalu Fusimalohi - will also have appeals against corruption suspensions heard on 2-3 February.
A sixth suspended official, Ismail Bhamjee of Botswana, has not appealed.
