Can a 17 year old have more than one job?

[PrinceHaz]

DD is out of college till September when she’s going to restart Lower VI, so in the meantime, she has plenty of flexibility to work part time hours.
Shes been offered a job and will start a trial next week. In the meantime, she has an interview for another tomorrow. If she gets that one, can she do 2 jobs?
What happens re: tax for 17 year olds, particularly if they do 2 jobs?
I'm aware my questions are Googleable but I haven’t found exactly the answers I’m looking for.

Open an online gateway and access all tax there. If you receive child benefit this will likely be stopped as she is no longer in full time education.

It would depend on the hours - https://www.citizensadvice.org.uk/work/children/check-your-rights-at-work-if-youre-under-18/#:~:text=You%20shouldn't%20usually%20be,available%20to%20do%20the%20work

Thanks for helpful advice.
