This isn't likely to be related to OpenWrt.

Do the devices have working internet access?

What types of devices and/or operating systems are on these hosts?

one device is Kodi media player, other 2 are windows pc, actually I have added OpenWrt firewall rule: Lan to Lan allow all and now all clients can ping fine!

This rule shouldn't actually do anything. I suspect if you remove it, your network will still work as expected.
