A regular switch+dimmer switch combo for several lights
You'll want a LED compatible, multi-way capable dimmer
In your case, you'll want a dimmer that's compatible with dimming Edison-base LED replacements, and also supports multi-way operation.  This is not something you want to cheap out on, or order from Amazon, by the way; your local home improvement/hardware store or electrical supply house should stock at least some of the Lutron, Leviton, Cooper/Eaton, or Legrand dimmer product lines, which all have suitable wallbox dimmers for your application.
(If you were considering something more sophisticated than a straightforward dimmer here, you'll need to provide us with more information, since we don't know how your wallboxes are configured, and sensor dimmers, &quot;smart&quot; dimmers, and some other dimming devices require a neutral reference at the switchbox, which isn't always available.)
