Regarding a rechargeable mens razor, hand luggage or suitcase?

Good evening 👋

I will be arriving to Don Mueang international airport on 3rd of June at 7pm with Air Asia.

Do you think catching a domestic flight DMK to Chiang Mai (Nok Air) at 9:15pm is feasible?

Knowing that I don't have checked luggages.

Also do I have to do the immigration process in DMK or in Chiang Mai?

Thanks for your assistance 🙏
