Apple products won't sync

I have 7 apple devices. They won't sync. I get emails on one device, not the others. Same with text messages. I've spent days on this.

I just want to use my phone to contact people. A device to read music from (like an iPad), and a watch to tell time with. I can do all of this without owning a Mac device.

I call Apple. Talk to someone with limited English skills (year, not politically correct here, just being honest) and eventually am placed on hold after being told I will speak to someone who knows how to fix it.

I'm a frustrated,
