Mmm okay let's see..
Just Corviknight and Cinderace is enough for beating him - Actually, a single Cinderace is good enough.
pyro miss still two shots it. alolan exeggutor is really quite pathetic although you will have to you turn out to something so you don't die to draco or something

Like sin said, Pyro Ball would've 2HKO Alo-Exeggutor. Here's a set for Cinder:
Cinderace @ Life Orb / Expert Belt
EVs: 252 Atk / 252 Spe / 4 SpD
Recommended Nature(s): Jolly / Adamant
Ability: Blaze / Libero
- Pyro Ball
- Bounce / U-Turn
- Some boosting move / Filler
- Filler
With Bounce and those EVs, this guy would surely OHKO Alo-Exeggutor. Pyro Ball kills the rest of your friend's team and with enough training, OHKOs even Exeggutor. U-Turn is also good to attack (If you choose to solo your friend with Cinder) or pivoting out to let your other Pokemon come in safely (If any).

However, another possible candidate for this is Weavile, which isn't in your team yet. Though Sneasels can be found easily in the Hammerlocke Hills.
Weavile @ Focus Sash / Expert Belt
EVs: 252 Atk / 252 Spe / 4 SpD
Recommended Nature(s): Jolly / Adamant
Ability: Pressure / Pickpocket
- Icicle Crash
- Knock Off
- Swords Dance / Filler
- Filler
Weavile instantly kills Alo-Exeggutor, which seems to be your main worry. It outspeeds pretty much everything in your friend's team, allowing it to solo him (except his Ferrothorn, but that can be handled by Cinderace). Icicle Crash and Knock Off are really good STABs and Sash is there just in case Ferro comes in and decides to attack you with a steel move.
Hope I helped!
