Is it related to the number of credit cards and the credit score?

People around me asked me to make a credit card, so I listened to it, so I got five of them without using them.

I think I need to pay attention to my credit score because I have a loan, but will it affect my credit score if I have a lot of credit cards?

I heard that there is an impact if it is issued by various credit card companies.
I heard that in the case of a card company, it's the same as just one issued.
