How many tourist visas can a Mexican passport holder enter Thailand within a calendar year?

Hi, I’m currently holding a Mexican passport with 3 ”tourist visa” stamps for the calendar year of 2023

1.) How many “tourist visas” per a calendar year is one passport holder usually allowed ? Is it 2, 3 or possibly 4 ?

2.) Is it possible with 3 tourists visa stamps on my current passport to enter under “visa on arrival” as Mexicans passport holders are given 15 days this December as I would like to spend Xmas in Thailand ?

3.) Is there a limit of entries for visa on arrival for Mexican passport holders ? I’ve don’t only one visa on arrival last year Dec.15 & was given stay till Jan.13 (30 days post covid)

4.) Will I be able to apply for a new tourist visa for the start of 2024 as it’s a new calendar year is that right ?

Plan to leave Asia by February. Trying to make travel plans for Xmas & NYE atm.

Much appreciated & thank you in advance !
