Combat Celebrant + Rionya, Fire Dancer

Overview
Yes. Rionya, Fire Dancer's beginning-of-combat effect can create tokens that are copies of another creature you control (for example, Combat Celebrant) . The tokens copy Combat Celebrant's printed text (including its exert ability) but not its current tapped/exerted state or attached Auras/Equipment [2021-04-16]. Because the tokens "gain haste" in Rionya's text, they can attack the turn they're created despite the summoning-sickness rule . Any time a Combat Celebrant (the original or a token copy) is exerted as it attacks, its exert effect untaps all other creatures you control and creates an additional combat phase after this one (and the additional-combat effect applies even if the creature doesn't survive the combat) [2017-04-18].
Step 1
At the beginning of combat on your turn, Rionya's triggered ability goes on the stack and can resolve to create X tokens that are copies of another target creature you control (you must target another creature you control) .
Step 2
When each token enters the battlefield, it is a creature under your control (not a creature spell resolving) and it is a printed copy of the chosen creature; per the ruling, it copies printed text but not tapped/exerted state or attachments [2021-04-16].
Step 3
Normally a creature can't attack the turn it comes under your control because of the summoning-sickness rule, but Rionya's tokens "gain haste" in her effect, so they can attack this turn despite .
Step 4
At Declare Attackers, you may declare the original Combat Celebrant and any token copies with haste as attackers. For any attacking Combat Celebrant (original or a token), you may choose to exert it as it attacks using its printed exert option.
Step 5
When you exert any Combat Celebrant (original or token) as it attacks, the exert effect untaps all other creatures you control and creates an additional combat phase after this one; that additional-combat effect still occurs even if the exerted creature doesn't survive the combat [2017-04-18].
Step 6
If multiple Combat Celebrants (original and/or tokens) are exerted during the same combat, each exert operation independently untaps your other creatures and will create additional combat phases (they stack as independent effects). Tokens created by Rionya will be exiled at the beginning of the next end step per Rionya's text.
Resolution
Rionya can make one or more tokens that are printed copies of Combat Celebrant at the beginning of combat . Those tokens have the printed exert ability (because tokens copy the printed card text) but do not copy tapped/exerted state or attachments [2021-04-16]. Because Rionya gives them haste, they may attack this turn despite . You may exert the original Celebrant or any token copy as they attack; exerting any of them will untap your other creatures and add an additional combat phase after the current combat [2017-04-18]. If multiple creatures are exerted, each exert effect still untaps other creatures and will create additional combat phases (they are independent). Exerted creatures will still skip their next untap step as usual.
