I’m wondering if i get an air tag for keeping my child safe, will it appear on other iphones that the air tag is nearby?

Transiently nearby, no. Extended time nearby or extended traveling with, yes.

What to do if you get an alert that an AirTag, set of AirPods, Find My network accessory, or compatible Bluetooth location-tracking device is with you - Apple Support

Yes. AirTags should not be used to track people.

okay thank you! I was considering it for when my child has contact with the other parent due to safety issues and to actually make sure my child is where the contact is meant to take place but i’m not wanting to alert the other parent, contact will normally be between 4-7 hours, will this alert the other parent within that time?

Talk to your attorney. This plan reeks of legal risks. And I’d expect your efforts here will be detected.
